 Motivation: It is difficult to do special things like SOS currently.  SOS
 requires observation of data in the matrix before it can be set up
 properly.  However, it must be done before the call to solve();
 Another symptom of this is the "writeMPS" call in the midst of the code
 commented out.
 The client of the model could call that on their own if they had a moment
 break in between the generation and the solving of the model

 Proposal:
 split "minimize"/"maximize"/... into a few bits:
 - attach()
 - solve()

 If absolutely necessary, I can fabricate minimize() and maximize() to
 behave as they do today.  This is a little tricky, but can be done.

 This would also allow folks to simply generate an MPS/LP file while
 debugging the model readily.  I find this to be extraordinarily helpful.
