Scott Sanderson	021e2da495	DEV: Separate FileCheckpointManager and GenericFileCheckpointManager. - Adds a `GenericCheckpointMixin` as a helper for implementing the two boundary-traversing Checkpoint API methods, `create_checkpoint` and `restore_checkpoint`. - `GenericFileCheckpointManager` is implemented as a subclass of `FileCheckpointManager` using `GenericCheckpointMixin`. Note that this is the safe subtyping relationship because of method signature contravariance: `FileCheckpointManager` accepts `FileContentsManager` in its method signatures type, whereas `GenericFileCheckpointManager` accepts any `ContentsManager`. - Moved Checkpoint-related classes to their own files.	11 years ago

DEV: Break get_checkpoint into separate methods.

One for notebooks and one for checkpoints.

STY: s/CheckpointManager/Checkpoints

It's easy to confuse CheckpointManager and ContentsManager.

DEV: Separate FileCheckpointManager and GenericFileCheckpointManager.

- Adds a `GenericCheckpointMixin` as a helper for implementing the two
  boundary-traversing Checkpoint API methods, `create_checkpoint` and
  `restore_checkpoint`.

- `GenericFileCheckpointManager` is implemented as a subclass of
  `FileCheckpointManager` using `GenericCheckpointMixin`.  Note that
  this is the safe subtyping relationship because of method
  signature *contra*variance: `FileCheckpointManager` accepts
  `FileContentsManager` in its method signatures type, whereas
  `GenericFileCheckpointManager` accepts any `ContentsManager`.

- Moved Checkpoint-related classes to their own files.
