Detailed Description
An MP\_Constraint represents a multiple point constraint in the domain. A multiple point constraint imposes a relationship between the displacement for certain dof at two nodes in the model, typically called the {retained} node and the {constrained} node: 
An MP\_Constraint is responsible for providing information on the relationship between the dof, this is in the form of a constraint Matrix, 
, and two ID objects, {retainedID} and {constrainedID} indicating the dof's at the nodes represented by
. For example, for the following constraint imposing a relationship between the displacements at node 
, the constrained node, with the displacements at node 
, the retained node in a problem where the x,y,z components are identified as the 0,1,2 degrees-of-freedom:
u_{1,x} = 2 u_{2,x} + u_{2,z}
u_{1,y} = 3 u_{2,z}
the constraint matrix is:
C_{cr} = \left[ \begin{array}{cc} 2 & 1 \ 0 & 3 \ \end{array} \right]
{constrainedID} = 
and {retainedID}

A pure virtual function. The component is to output itself to the output stream {s}. The integer {flag} can be used to select just what should be output, by default 
is passed.

This is a pure virtual method, one must be written for each instantiable subclass of MovableObject. Each object has to receive the data needed to be able to recreate itself in the new process after it has been sent through {theChannel}. If the object is an aggregation containing other objects, new objects of the correct type can be constructed using {theBroker}. To return
if successful or a 
if not.
