http://nvie.com/posts/a-successful-git-branching-model/

Commit conventions:
- Document commits clearly and separately.
- Refer to issues with `Refs #<issue_number>`.
- Open an issue first if no issue exists for a change.
- Do not address more than one issue per commit or PR.
- Document changes in CHANGELOGs in a separate commit before PR.
- Prefix summary line with `<package_name>: ` for package-specific commits.
- Ensure changes conform to the coding style.

### Yampa API Documentation

Source: https://github.com/ivanperez-keera/yampa/blob/develop/yampa/README.md

Comprehensive API documentation for Yampa, detailing its functions, types, and usage. This includes information on signal functions, event handling, and integration with various backends.

```APIDOC
Yampa API Documentation:

Signal Functions (SF):
  SF a b
    Represents a function from input of type 'a' to output of type 'b' over time.
    Core component of Yampa for defining reactive behavior.

Basic SF Combinators:
  pure :: a -> SF s a
    Creates an SF that always produces a constant output.
  (<*>) :: SF s (a -> b) -> SF s a -> SF s b
    Applies a function output by one SF to the input of another SF.
  arr :: (a -> b) -> SF s b
    Converts a pure function into an SF.
  >>> :: SF s a -> SF s b -> SF s (a, b)
    Combines two SFs, taking inputs from both and producing a pair of outputs.

Event Handling:
  never :: SF s a
    An SF that never produces an output.
  now :: a -> SF s a
    An SF that produces an output once.
  after :: Double -> a -> SF s a
    An SF that produces an output after a specified delay.
  edge :: (a -> Bool) -> SF s a -> SF s a
    Produces an output only when the predicate transitions from False to True.

Integration with Backends:
  (Specific backend integration details would be listed here, e.g., SDL, OpenGL, GLFW, HTML Canvas, Gloss)
  Example for Gloss:
    play :: Display -> Color -> Int -> World -> (World -> Picture) -> (Event -> World -> World) -> World -> IO ()
      Initializes and runs a Gloss window with Yampa integration.
      Parameters:
        Display: Window display settings.
        Color: Background color.
        Int: Number of simulation steps per second.
        World: Initial game state.
        (World -> Picture): Function to render the game state.
        (Event -> World -> World): Function to handle user input and update the game state.
        World: The final game state.
      Returns: IO ()

Testing and Debugging:
  (Details on QuickCheck integration and time-travel debugging would be listed here)
  Example for QuickCheck:
    quickCheck :: Testable prop => prop -> IO ()
      Runs QuickCheck tests on Yampa signal functions.
      Requires properties defined using QuickCheck's interface.
