* 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. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24351 a95241bf-73f2-0310-859d-f6bbb57e9c96
