MAYBE

Inspired by Lift's Box, Haskell's Maybe and Scala's Option.

A few noteable characteristics:

• Maybe() is a polymorphich constructor that Does The Right Thing, no matter the input.
• get is only provided for a Just value, not in the general Maybe API.
• map on a Just Does The Right Thing, even if the calling function explodes.

Latest release is "com.ckkloverdos" % "maybe" % "0.5.0" from Maven Central, compiled with Scala 2.9.1.
