Note that this file has three already-started Hmmm programs, named
Example1, Problem1, and Random. See below for how to run them.
This function will then load the libraries it needs,
assemble the Hmmm program into machine language (bits), and
then run it... . User input will come from the command-line.
So, to use this function, for example, in ipython:
In[]: run hw6pr1.py
In[]: Hmmm( Example1 )
... the Hmmm program should be assembled into machine code ...
... and then run. (Usually you'll say n (no) to the debugging mode.)
