//! @brief Handle the constraints.
//!
//! Determines the number of FE\_Elements and DOF\_Groups needed from the
//! Domain (a one to one mapping between Elements and FE\_Elements and
//! Nodes and DOF\_Groups) Creates two arrays of pointers to store the
//! FE\_elements and DOF\_Groups, returning a warning message and a \f$-2\f$
//! or \f$-3\f$ if not enough memory is available for these arrays. Then the
//! object will iterate through the Nodes of the Domain, creating a
//! DOF\_Group for each node and setting the initial id for each dof to
//! \f$-2\f$ if no SFreedom\_Constraint exists for the dof, or \f$-1\f$ if a
//! SFreedom\_Constraint exists or \f$-3\f$ if the node identifier is in {\em
//! nodesToBeNumberedLast}. The object then iterates through the Elements
//! of the Domain creating a FE\_Element for each Element, if the Element
//! is a Subdomain setFE\_ElementPtr() is invoked on the Subdomain
//! with the new FE\_Element as the argument. If not enough memory is
//! available for any DOF\_Group or FE\_element a warning message is
//! printed and a \f$-4\f$ or \f$-5\f$ is returned. If any MFreedom\_Constraint
//! objects exist in the Domain a warning message is printed and \f$-6\f$ is
//! returned. If all is successful, the method returns the number of
//! degrees-of-freedom associated with the DOF\_Groups in {\em
//! nodesToBeNumberedLast}.
