Updated mailroom program from last week cleaning up some parts of the code after feedback from Chris.  Also refactored it to use dictionaries instead of lists plus some other additions as part of this week's assignment.
My first working version of the trigram assignment.  It is pretty ugly at this stage because I didn't break things out into functions or write a nice docstring, etc.  But it appears to do what it should for the hardcoded 2 word key.  I will clean up if I have time.
