This directory contains the various states that a Repository model can assume. Each state subclasses State, which provides each state with:

• Trivial implementations of the state-dependent Repository functionality that return "empty" results where possible; Promises that resolve to empty arrays, null-object Remote or Branch implementations, false. This allows the UI components to freely query the current Repository for data regardless of whether an actual git repository exists or not.
• Action and transition methods that throw exceptions or reject Promises.
• UI state probe methods to allow individual states to customize the way that certain UI components respond while each state is active. For example, if showGitTabLoading is overridden to return false, the .is-loading class is added to the Git tab DOM node to allow it to be styled differently.

Here's the current state transition diagram:

Only the initial states (Absent, AbsentGuess, Loading, and LoadingGuess) are exported from the directory module.
