Updated readme with a note on how to install, dependencies used by
pyKwalify and the supported python version.
Fixed the cli by renaming the input argument to make more sense then
before. Fixed a bug where if no cli argument was set it would go into
the Core starting to parse an invalid file.
Removed unused exceptions and renamed them to be easier to use.
Renamed the exception used by Core.py after the renaming.
Renamed some functions to private function names.
