Initial commit of empty playground
Created a cycloid class. Magic
Added a cycloid view to the playground

This doesn't currently work :( but I reckon that this is due to the
playground implementation not allowing animation of UIView objects yet.
May try it on an NSView
Move directory to iOS in prep for an OSX version
Translate to an OSX playground so that the demo works

This should demo what it will be like once iOS works :)

Introduction to playgrounds completed
Update line wrapping
Completed the writeup for playgrounds
