Detailed Description

Implements a constraint of the form lb <= x <= ub .

Note: the base Constraint class (as implemented at the moment) could play this role. But this class enforces that it is ONLY a bounding box constraint, and not something more general. Some solvers use this information to handle bounding box constraints differently than general constraints, so use of this form is encouraged.
