* Test to see how much needs to be ported for other platforms (if at all)
* Setup as api.
* Provide binaries in the release page for github. (debug and release builds)
* Directive to ignore comments (with a way to specify the comment signature). Right now comments that meet the signature of words or namespaces are refactored.
