  Add unit tests for index manipulation Three new unit tests, t06XX files have been added. t0601-read: tests for loading index files from disk, for creating in-memory indexes and for accessing index entries. t0602-write: tests for writing index files back to disk t0603-sort: tests for properly sorting the entries array of an index Two test indexes have been added in 'tests/resources/': test/resources/index: a sample index from a libgit2 repository test/resources/gitgit.index: a sample index from a git.git repository (includes TREE extension data) Signed-off-by: Vicent Marti <tanoku@gmail.com>
