Fix tree node collection type

Fixes some tree rendering problems where lines were not properly drawn
at some levels during some circumstances.

* Change the API back to only allow one root.
* Now uses a stack based approach to rendering instead of recursion.
* Removes the need for measuring the whole tree in advance.
  Leave this up to each child to render.

+
+## Prerequisites
+
+By contributing to Spectre.Console, you assert that:
+
+* The contribution is your own original work.
+* You have the right to assign the copyright for the work (it is not owned by your employer, or
+  you have been given copyright assignment in writing).
+* You [license](https://github.com/spectresystems/spectre.console/blob/main/LICENSE) the contribution under the terms applied to the rest of the Spectre.Console project.
+* You agree to follow the [code of conduct](https://github.com/spectresystems/spectre.console/blob/main/CODE_OF_CONDUCT.md).
+
+## Definition of trivial contributions
+It's hard to define what is a trivial contribution. Sometimes even a 1 character change can be considered significant.
+Unfortunately because it can be subjective, the decision on what is trivial comes from the maintainers of the project
+and not from folks contributing to the project.
+
+What is generally considered trivial:
+
+* Fixing a typo.
+* Documentation changes.
+
+## Code
+### Code style
+
+Normal .NET coding guidelines apply.
+See the [Framework Design Guidelines](https://msdn.microsoft.com/en-us/library/ms229042%28v=vs.110%29.aspx) for more information.
+
+### Dependencies
+
+The assembly `Spectre.Console` should have no dependencies except the .NET BCL library.
+
+### Unit tests
+
+Make sure to run all unit tests before creating a pull request.
+Any new code should also have reasonable unit test coverage.
+
+## Contributing process
+### Get buyoff or find open community issues or features
+
+ * Through GitHub, or through the [GitHub discussions](https://github.com/spectresystems/spectre.console/discussions) (preferred),
+   you talk about a feature you would like to see (or a bug), and why it should be in Spectre.Console.
+   * If approved through the GitHub discussions, ensure an accompanying GitHub issue is created with
+     information and a link back to the discussion.
+  * Once you get a nod from someone in the Spectre.Console Team, you can start on the feature.
+  * Alternatively, if a feature is on the issues list with the
+   [Up For Grabs](https://github.com/spectresystems/spectre.console/labels/up-for-grabs) label,
+   it is open for a community member (contributor) to patch. You should comment that you are signing up for it on
+   the issue so someone else doesn't also sign up for the work.
+
+### Set up your environment
+
+ * You create, or update, a fork of `spectresystems/spectre.console` under your GitHub account.
+ * From there you create a branch named specific to the feature.
+ * In the branch you do work specific to the feature.
+ * Please also observe the following:
+    * No reformatting
+    * No changing files that are not specific to the feature.
+    * More covered below in the **Prepare commits** section.
+ * Test your changes and please help us out by updating and implementing some automated tests.
+   It is recommended that all contributors spend some time looking over the tests in the source code.
+   You can't go wrong emulating one of the existing tests and then changing it specific to the behavior you are testing.
+ * Please do not update your branch from the main branch unless we ask you to. See the responding to feedback section below.
+
+### Prepare commits
+This section serves to help you understand what makes a good commit.
+
+A commit should observe the following:
+
+ * A commit is a small logical unit that represents a change.
+ * Should include new or changed tests relevant to the changes you are making.
+ * No unnecessary whitespace. Check for whitespace with `git diff --check` and `git diff --cached --check` before commit.
+ * You can stage parts of a file for commit.
+
+### Submit pull request
+Prerequisites:
+
+ * You are making commits in a feature branch.
+ * All code should compile without errors or warnings.
+ * All tests should be passing.
+
+Submitting PR:
+
+ * Once you feel it is ready, submit the pull request to the `spectresystems/spectre.console` repository against the `main` branch
+   unless specifically requested to submit it against another branch.
+   * In the case of a larger change that is going to require more discussion,
+     please submit a PR sooner. Waiting until you are ready may mean more changes than you are
+     interested in if the changes are taking things in a direction the maintainers do not want to go.
+ * In the pull request, outline what you did and point to specific conversations (as in URLs)
+   and issues that you are resolving. This is a tremendous help for us in evaluation and acceptance.
+ * Once the pull request is in, please do not delete the branch or close the pull request
+   (unless something is wrong with it).
+ * One of the Spectre.Console team members, or one of the maintainers, will evaluate it within a
+   reasonable time period (which is to say usually within 1-3 weeks). Some things get evaluated
+   faster or fast tracked. We are human and we have active lives outside of open source so don't
+   fret if you haven't seen any activity on your pull request within a month or two.
+   We don't have a Service Level Agreement (SLA) for pull requests.
+   Just know that we will evaluate your pull request.
+
+### Respond to feedback on pull request
+
+We may have feedback for you to fix or change some things. We generally like to see that pushed against
+the same topic branch (it will automatically update the Pull Request). You can also fix/squash/rebase
+commits and push the same topic branch with `--force` (it's generally acceptable to do this on topic
+branches not in the main repository, it is generally unacceptable and should be avoided at all costs
+against the main repository).
+
+If we have comments or questions when we do evaluate it and receive no response, it will probably
+lessen the chance of getting accepted. Eventually, this means it will be closed if it is not accepted.
+Please know this doesn't mean we don't value your contribution, just that things go stale. If in the
+future you want to pick it back up, feel free to address our concerns/questions/feedback and reopen
+the issue/open a new PR (referencing old one).
+
+Sometimes we may need you to rebase your commit against the latest code before we can review it further.
+If this happens, you can do the following:
+
+ * `git fetch upstream` (upstream remote would be `spectresystems/spectre.console`)
+ * `git checkout main`
+ * `git rebase upstream/main`
+ * `git checkout your-branch`
+ * `git rebase main`
+ * Fix any merge conflicts
+ * `git push origin your-branch` (origin would be your GitHub repo or `your-github-username/spectre.console` in this case).
+   You may need to `git push origin your-branch --force` to get the commits pushed.
+   This is generally acceptable with topic branches not in the mainstream repository.
+
+The only reasons a pull request should be closed and resubmitted are as follows:
+
+ * When the pull request is targeting the wrong branch (this doesn't happen as often).
+ * When there are updates made to the original by someone other than the original contributor.
+   Then the old branch is closed with a note on the newer branch this supersedes #github_number.
+
+## Other general information
+If you reformat code or hit core functionality without an approval from a person on the Spectre.Console Team,
+it's likely that no matter how awesome it looks afterwards, it will probably not get accepted.
+Reformatting code makes it harder for us to evaluate exactly what was changed.
+
+If you do these things, it will be make evaluation and acceptance easy.
+Now if you stray outside of the guidelines we have above, it doesn't mean we are going to ignore
+your pull request. It will just make things harder for us.
+Harder for us roughly translates to a longer SLA for your pull request.

+Title: Introduction
+Order: 1
+---
+
+`Spectre.Console.Cli` is a modern library for parsing command line arguments. While it's extremely
+opinionated in what it does, it tries to follow established industry conventions, and draws
+its inspiration from applications you use everyday.
+
+# How does it work?
+
+The underlying philosophy behind `Spectre.Console.Cli` is to rely on the .NET type system to 
+declare the commands, but tie everything together via composition.
+
+Imagine the following command structure:
+
+* dotnet *(executable)*
+  * add `[PROJECT]`
+    * package `<PACKAGE_NAME>` --version `<VERSION>`
+    * reference `<PROJECT_REFERENCE>`
+
+For this I would like to implement the commands (the different levels in the tree that 
+executes something) separately from the settings (the options, flags and arguments), 
+which I want to be able to inherit from each other.
+
+## Specify the settings
+
+We start by creating some settings that represents the options, flags and arguments
+that we want to act upon.
+
+```csharp
+public class AddSettings : CommandSettings
+{
+    [CommandArgument(0, "[PROJECT]")]
+    public string Project { get; set; }
+}
+
+public class AddPackageSettings : AddSettings
+{
+    [CommandArgument(0, "<PACKAGE_NAME>")]
+    public string PackageName { get; set; }
+
+    [CommandOption("-v|--version <VERSION>")]
+    public string Version { get; set; }
+}
+
+public class AddReferenceSettings : AddSettings
+{
+    [CommandArgument(0, "<PROJECT_REFERENCE>")]
+    public string ProjectReference { get; set; }
+}
+```
+
+## Specify the commands
+
+Now it's time to specify the commands that act on the settings we created
+in the previous step.
+
+```csharp
+public class AddPackageCommand : Command<AddPackageSettings>
+{
+    public override int Execute(AddPackageSettings settings, ILookup<string, string> remaining)
+    {
+        // Omitted
+    }
+}
+
+public class AddReferenceCommand : Command<AddReferenceSettings>
+{
+    public override int Execute(AddReferenceSettings settings, ILookup<string, string> remaining)
+    {
+        // Omitted
+    }
+}
+```
+
+## Let's tie it together
+
+Now when we have our commands and settings implemented, we can compose a command tree
+that tells the parser how to interpret user input.
+
+```csharp
+using Spectre.Console.Cli;
+
+namespace MyApp
+{
+    public static class Program
+    {
+        public static int Main(string[] args)
+        {
+            var app = new CommandApp();
+
+            app.Configure(config =>
+            {
+                config.AddBranch<AddSettings>("add", add =>
+                {
+                    add.AddCommand<AddPackageCommand>("package");
+                    add.AddCommand<AddReferenceCommand>("reference");
+                });
+            });
+
+            return app.Run(args);
+        }
+    }
+}
+```
+
+# So why this way?
+
+Now you might wonder, why do things like this? Well, for starters the different parts
+of the application are separated, while still having the option to share things like options,
+flags and arguments between them.
+
+This make the resulting code very clean and easy to navigate, not to mention to unit test.
+And most importantly at all, the type system guides me to do the right thing. I can't configure 
+commands in non-compatible ways, and if I want to add a new top-level `add-package` command 
+(or move the command completely), it's just a single line to change. This makes it easy to 
+experiment and makes the CLI experience a first class citizen of your application.

+Title: Migrate from Spectre.Cli
+Order: 2
+---
+
+The functionality in `Spectre.Cli` has been moved into the `Spectre.Console`
+library. If you're using `Spectre.Cli`, you will need to migrate to ensure
+that you get updates or fixes.
+
+## 1. Remove Spectre.Cli NuGet package
+
+Start with removing the `Spectre.Cli` package reference from your project(s).
+
+```text
+> dotnet remove package Spectre.Cli
+```
+
+## 2. Add Spectre.Console NuGet package
+
+Add the [Spectre.Console](https://www.nuget.org/packages/spectre.console) NuGet package to your project(s).
+
+```text
+> dotnet add package Spectre.Console
+```
+
+## 3. Change using statements
+
+Change all using statements from `Spectre.Cli` 
+to `Spectre.Console.CLi`.
+
+```diff
+- using Spectre.Cli;
++ using Spectre.Console.Cli;
+```
+
+# Breaking Changes
+
+In the process of moving `Spectre.Cli`, there have been some minor breaking changes.
+
+## Spectre.Cli.Exceptions namespace moved
+
+All exceptions have been moved from the `Spectre.Cli.Exceptions` namespace to
+  the `Spectre.Console.Cli` namespace.
+
+```diff
+- using Spectre.Cli.Exceptions;
