* Got rid of class ObjFunctionSummand. Both the constraint summands and
the objective function summands are now stored using class Summand.
* Some method names are more BeOS compliant now: SetX instead of ChangeX.
* linprog test code now uses new AddConstraint methods.
* CalculateMinSize and CalculateMaxSize did not free the memory they
allocated.
* Removed inappropriate setter and getter methods.
* Memory allocated in class Constraint is freed now.
* Other small changes.
