Detailed Description
LagrangeMP\_FE is a subclass of FE\_Element used to enforce a multi point constraint, of the form 
, where 
are the constrained degrees-of-freedom at the constrained node, 
are the retained degrees-of-freedom at the retained node and 
a matrix defining the relationship between these degrees-of-freedom.
To enforce the constraint the following are added to the tangent and the residual:
at the locations corresponding to the constrained degree-of-freedoms specified by the MP\_Constraint, i.e. 
, and the lagrange multiplier degrees-of-freedom introduced by the LagrangeConstraintHandler for this constraint, 
. Nothing is added to the residual. \
