Tag Docile v0.0.1

Hi, a quick summary:

This package allows methods, macros, type, etc. to be documented and for that documentation to be searchable from the REPL. Might be some slightly rough corners in places, but I've been putting off tagging this for too long now :)

Any feedback welcome.

Also: what's the process for depreciating this once there's builtin docstrings in Julia herself?
