Uncrustify first pass
Rewrite of UICollectionViewFlowLayoutDelegate 
methods
Simplified handlePanGesture some refactorings,
get a more compact code look
Simplify handleScroll: and refactor some other 
stuff to a less verbose look
Further progress on getting things readable and
manageable.
Some more recoarsements (opposite of refinements)
to make this almost useable to me now.
