 Swift Programming Language Guide
 "A Swift Tour" Solutions
 https://developer.apple.com/library/prerelease/ios/documentation/Swift/Conceptual/Swift_Programming_Language/GuidedTour.html#//apple_ref/doc/uid/TP40014097-CH2-XID_1
 
 These are the solutions to all the "experiments" in the pre-release Swift Programming Guide 
 (released on the same day Apple announced Swift). A couple of things worth noting:
 
 1. Swift syntax, e.g. array declarations, has changed since I releasd these. So this code will 
    probably cause some errors when you paste it into a playground. Should be easy enough to fix
