Derived class within the Constraints hierarchy which employs relaxation of discrete variables.
Derived variable constraints classes take different views of the design, uncertain, and state variable types and the continuous and discrete domain types. The RelaxedVarConstraints derived class combines continuous and discrete domain types through integer relaxation. The branch and bound method uses this approach (see Variables::get_variables(problem_db) for variables type selection; variables type is passed to the Constraints constructor in Model).

standard constructor
In this class, a relaxed data approach is used in which continuous and discrete arrays are combined into a single continuous array (integrality is relaxed; the converse of truncating reals is not currently supported but could be in the future if needed). Iterators which use this class include: BranchBndOptimizer.
