Detailed Description
The ParallelNumberer numbers the dof of a partitioned domain, where the partitions are on different processors and each processor has a ParallelNumberer.
The ParalellNumberer sitting on P0, collects each partition graph from P1 through Pn-1, merges them into 1 large graph, & then numbers this graph. The ParallelNumberers sitting on P1 through Pn-1 then receive the mapping info for the dof tag and dof numbering from P0.

Invoked to assign the equation numbers to the dofs.
Invoked to assign the equation numbers to the dofs in the DOF_Groups and the FE_Elements, ensuring that the dof's in the DOF_Group whose tag is given by {lastDOF_Group} are numbered last in a \(-2\) or \(-3\) group. The initial values of these equation numbers have been set by the ConstraintHandler object to be \(-1\), \(-2\) or \(-3\), all dofs with a \(-3\) are to be assigned higher equation numbers than those assigned a \(-2\). To set the numEqn in the AnalysisModel and to return the number of equations numEqn if successful, a negative number if not. This base class performs the ordering by getting an ID containing the ordered DOF_Group tags, obtained by invoking {number(theModel- \(>\)getDOFGroupGraph(), lastDOF_Group)} on the GraphNumberer, theGraphNumberer, passed in the constructor. The base class then makes two passes through the DOF_Group objects in the AnalysisModel by looping through this ID; in the first pass assigning the equation numbers incrementally to any degree-of-freedom marked with a \(-2\) and in the second pass assigning the equation numbers incrementally to any degree-of-freedom marked with a \(-3\). It then iterates through the FE_Elements in the AnalsisModel invoking {setID()} on each object. Finally {setNumEqn(numEqn)} is invoked on the AnalysisModel. Return numEqn if successful, a warning message and a negative number is returned if an error occurs; \(-1\) is returned if setLinks() has not yet been invoked, \(-2\) if no GraphNumberer was passed in the constructor, \(-3\) if the number of {DOF_Groups} in AnalysisModel and size of ID returned are not the same, and a \(-4\) if there is no DOF_Group corresponding to one of the tags given in the ID.
Reimplemented from XC::DOF_Numberer.

Invoked to assign the equation numbers to the dofs.
Invoked to assign the equation numbers to the dofs in the DOF_Groups and the FE_Elements, ensuring that the dof's in the DOF_Groups whose tag is given in {lastDOF_Groups} are numbered last in a \(-2\) or \(-3\) group. The initial values of these equation numbers have been set by the ConstraintHandler object to be \(-1\), \(-2\) or \(-3\), all dofs with a \(-3\) are to be assigned higher equation numbers than those assigned a \(-2\). To set the numEqn in the AnalysisModel and to return the number of equations numEqn if successful, a negative number if not.
This method in the base class is almost identical to the one just described. The only difference is that the ID identifying the order of the DOF_Groups is obtained by invoking {number(theModel- \(>\)getDOFGroupGraph(), lastDOF_Groups)} on the GraphNumberer.
