Walkthrough
## Walkthrough
The changes primarily involve refactoring the registration methodology within various classes in the codebase to use `GetRootManager()` instead of directly accessing the singleton `FairRootManager::Instance()`. This update has been applied across multiple examples, templates, and core classes, likely to improve code modularity and maintainability.

Tips
### Chat
There are 3 ways to chat with [CodeRabbit](https://coderabbit.ai):
- Review comments: Directly reply to a review comment made by CodeRabbit. Example:
- `I pushed a fix in commit .`
- `Generate unit testing code for this file.`
- `Open a follow-up GitHub issue for this discussion.`
- Files and specific lines of code (under the "Files changed" tab): Tag `@coderabbitai` in a new review comment at the desired location with your query. Examples:
- `@coderabbitai generate unit testing code for this file.`
- `@coderabbitai modularize this function.`
- PR comments: Tag `@coderabbitai` in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
- `@coderabbitai generate interesting stats about this repository and render them as a table.`
- `@coderabbitai show all the console.log statements in this repository.`
- `@coderabbitai read src/utils.ts and generate unit testing code.`
- `@coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.`
- `@coderabbitai help me debug CodeRabbit configuration file.`
Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
### CodeRabbit Commands (invoked as PR comments)
- `@coderabbitai pause` to pause the reviews on a PR.
- `@coderabbitai resume` to resume the paused reviews.
- `@coderabbitai review` to trigger an incremental review. This is useful when automatic reviews are disabled for the repository.
- `@coderabbitai full review` to do a full review from scratch and review all the files again.
- `@coderabbitai summary` to regenerate the summary of the PR.
- `@coderabbitai resolve` resolve all the CodeRabbit review comments.
- `@coderabbitai configuration` to show the current CodeRabbit configuration for the repository.
- `@coderabbitai help` to get help.
Additionally, you can add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed.
### CodeRabbit Configration File (`.coderabbit.yaml`)
- You can programmatically configure CodeRabbit by adding a `.coderabbit.yaml` file to the root of your repository.
- Please see the [configuration documentation](https://docs.coderabbit.ai/guides/configure-coderabbit) for more information.
- If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: `# yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json`
### Documentation and Community

- Follow us on [X/Twitter](https://twitter.com/coderabbitai) for updates and announcements.
Especially classes deriving from FairDetector and implementing the Register member function need access to FairrootManager. Give them a proper getter.
