XFEM: Starting to implement mapping of primary variables and state
variables for XFEM simulations. (Much work still remains though.)
XFEMStatic: Disabled setting of values from dof map when mapping between
domains is active.
XFEM: Added test case for variable mapping.
Structural element and subclasses: changed syntax of computeNMatrixAt so
that it takes local coordinates as input instead of a Gauss point.
XFEM: Small cleanup in primary variable mapper.
StructuralElement: Implemented a generic version of computeNMatrixAt
that works for many elements.
Fixed merge conflicts.
XFEM: Modified the inclusion enrichment item so that it has a cross
section instead of a material.
StructuralCrossSection: implemented createMaterialStatus() to allow
cross sections to create a material status based on the correct
material.
