GRBModel::addRange()
Add a single range constraint to a model. A range constraint
states that the value of the input expression must be between
the specified lower and upper bounds in any solution.
Note that range constraints are stored internally as equality
constraints. We add an extra variable to the model to capture the
range information. Thus, the
Sense
attribute on a range constraint will always be GRB_EQUAL.

upper: Upper bound for linear expression.
name (optional): Name for new constraint.
Return value:
New constraint object.
