#85: Problem with CBC-AMPL Interface

 I am encountering the following problem:
 I start CBC through AMPL and can see that the call from AMPL works
 correctly (correct dimensions and correct objective after finishing
 optimization). However, AMPL does not receive the updated values from CBC,
 the AMPL's variables remain set to the values that they had when calling
 CBC.
