FailFastDeletionVisitor added
Merge pull request #2 from TheItachiUchiha/master

FailFastDeletionVisitor skeleton
Add jimfs as a test dependency
Use marschall/memoryfilesystem instead of jimfs

Unlike jimfs, it supports POSIX file permissions; we want that for tests.
Add MemoryfsExample for future copy/deletion tests
Add README
Add CustomAssertions to test package (for shouldHaveThrown())
:octocat: Added .gitattributes
Implemented comparison of Path2 root with Path1 all possible roots

Added test cases as well.
