Hi All,

I'm very happy to announce the a new release of Mush, a light weight 
dependency injection framework aimed at enabling the easy testing and 
re-use of chunks of code that make up scripts.

This release rounds out a some more rough edges after even more real 
world use:

- The 'nothing' singleton is now used  instead of None for marking
   return types, fixing a bug that occurred when a callable tried to
   type-map a result that was None.

- Add an after() type wrapper for callables that need to wait
   until after a resource is used but that can't accept that resource
   as a parameter.

For a worked example of how to use Mush to reduce the copy'n'paste in 
your scripts, please see here:
