v0.1.2.0

Added atom and mkAtomParser helper functions for new user-defined atom types.
New parsers for various atom types:
- Exported parsers for individual Haskell literals, to allow building new variations on the HaskLike atom type.
- Added syntaxes for arbitrary-base numeric literals in the style of Common Lisp and M4
Added a suite of basic QuickCheck tests
Compatibility fix: GHC 7.8 didn't allow type signatures on pattern synonyms.

v0.1.1.0

Strongly considered but did not keep a changelog. …sorry.
