ModifiedFilesCache (Gerrit Review Plugin API Documentation)

All Known Implementing Classes:

ModifiedFilesCacheImpl
```
public interface ModifiedFilesCache
```
A cache for the list of Git modified files between 2 commits (patchsets) with extra Gerrit logic.
The loader uses the underlying GitModifiedFilesCacheImpl to retrieve the git modified files.
If the ModifiedFilesCacheKey.aCommit() is equal to Constants.EMPTY_TREE_ID, the diff will be evaluated against the empty tree, and the result will be exactly the same as the caller can get from GitModifiedFilesCache.get(GitModifiedFilesCacheKey)
