dmocks version 0.1

[Christopher Wright]

For anyone who doesn't know what mock objects are and wants to, there's 
Wikipedia: http://en.wikipedia.org/wiki/Mock_object

In brief, a mock object allows you to test how one class interacts with 
another, and test the functionality of each class independently of the 
rest. It does so by acting like an object that the class you are testing 
uses, but recording and checking which methods are called and returning 
values according to what the programmer explicitly told it to.
