Merge tag '0.2.0' into develop

Release 0.2.0

Reworking the API atop multimethods
Fix #3
Use Grimoire 0.3.X related & notes files
Fix read-related

This patch corrects the behavior of read-related so that it will parse a
Grimoire 0.3.X file of fully qualified symbols correctly rather than
assuming related files are filled with Thing URIs
Link to latest, not listed version

This patch tweaks read-related so that rather than linking to the
version where the symbol(s) are listed as related are listed, things
sharing the version of the thing for which related symbols are requested
will be returned.

Note that this may generate invlalid links, however it is likely to give
more current results and so is provided.
Add arities that behave as partials of ->T
Partion & clean filesystem api
Bumped version to 0.3.0
