Simplifying parsers, prepping for v0.1

- Parsers for each doc type are now in a single file under the
`lib/parsers` directory
- Added new DSL functions for parsing (will be further abstracted to
core lib in the future)
- Adding placeholders for generators, renderers
- Cleaning up JSHint issues
Restructuring for next release

Tests and general functionality might be broken in the meantime.
Restoring basic functionality

- Lib is now functional, consistent with release v0.0.19
Updating README to reflect v0.1 interface
Adding `data.json()` to C32, CCDA parsers
JavaScript conflates dates and datetimes in an unfortunate manner. This
commit customizes our JSON.Stringify call so that when we receive
date-level precision from our source document, we only output date-level
precision in our JSON. This also makes our test suite no longer dependent
on running in Pacific Standard Time. It is a breaking change for our
JSON API.

There are also a couple miscellaneous fixes (a typo in the procedures
code and in the Gruntfile)
Adding `parseName` and `parseAddress` from #94

- Both contained in the `Documents` module
- Big ups to @sankarravi for this!

Breaking out document parsers by section
Making `CCDA` and `C32` parsers proper modules
