 Ok. The user should not even have to do that (create empty matrix).

 Hi Matt/Ted:

 I **think** I figured out my answer to question 1 in the previous email.
 In the GAP example, I just commented out the lines of code where the
 knapsack coefficients are explicitly generated. I guess just having

     model->M = new CoinPackedMatrix(false, 0.0, 0.0);
     CoinAssertHint(model->M, "Error: Out of Memory");
     model->M->setDimensions(0, nCols);

 does the trick, but it is not clear from the documentation what I should
 be doing.
