Removing FCYAsserts
Cache
Optimizations regarding nil values in dictionaries and how keys are getting accessed.
Adding Notes.md
Updating AFNetworking dependency

ONLY Podfile
iOS Upgrade + full compatibility with AFNetworking 2.0

A few things here and there can still be optimized for AFNetworking 2.0
Network optimizations + property mapper tryouts

mostly network error handling
property mapper for one example
also a few comments changed to new format
First big change to property mapper
Last convert to property mapper and small cleanups

LFMArtistGetTopAlbums convert to property mapper
Various little optimizations

most notably the boolean conversion
renaming classes
Adding LFMArtist
Idea for LFMData modeling
completion handler

refactoring to just use one completion handler
Request generation refactoring

refactored the way default parameters get added
needs support from AFNetworking though...

other misc todos and cleanups
