Release Name: 0.2.1

Notes:
Safer is an umbrella library, with components designed to make it simple to
verify and improve the safety of your ruby code.  There are at present two
modules under the safer umbrella:

[Safer::IVar]     generates specially-named accessor functions
                           for class instance variables.
[Safer::Protocol] is used to provide a ruby analogue to
                           Objective-C Protocols (which are similar to
                           Java interfaces, but do not require
                           inheritance).
