Detailed Description
PenaltyConstraintHandler is a constraint handler that deals with both single and multi freedom constraints using the penalty method.
This is done by, in addition to creating a DOF_Group object for each Node and an FE_Element for each Element in the Domain, creating either a PenaltySFreedom_FE or a PenaltyMFreedom_FE object for each constraint in the Domain. It is these objects that enforce the constraints by modifying the tangent matrix and residual vector.

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, SFreedom_Constraints and PenaltySFreedom_FEs, MFreedom_Constraints and PenaltyMFreedom_FEs and Nodes and DOF_Groups). Creates two arrays of pointers to store the FE_Elements and DOF_Groups, returning a warning message and a \(-2\) or \(-3\) 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 \(-2\) or \(-3\) if the node identifier is in {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 \(-4\) or \(-5\) is returned. The object then iterates through the SFreedom_Constraints of the Domain creating a PenaltySFreedom_FE for each constraint, using the Domain, the constraint and alphaSP as the arguments in the constructor. The object then iterates through the MP_Constraints of the Domain creating a PenaltyMP_FE for each constraint, using the Domain, the constraint and alphaMP as the arguments in the constructor. Finally the method returns the number of degrees-of-freedom associated with the DOF_Groups in {nodesToBeNumberedLast}.
