This implements the two remaining tags and removes the author tag. Had to do some deeper plumbing because options per function signature were not being passed along from YARD
This implements the author tag. We also claim to support the 'raise' and 'option' tags, but I don't know that we need to. This also consolidates some code in base.rb and adds docs
This change does a few things:
1. Fixes up new api handler to return the stuff we want
2. Adds all the logic to parse YARD registries into markdown
3. Adds templates for markdown
4. Changes Face cli to use a --format option that can be used for either
markdown or json
