Increased the tolerance somewhat.
Fixed to Shell7BaseXFEM can export the level sets associated with the ei's.

Fixed sign errors in beam3d. Numerical integration for both beam2d and beam3d (to enable varying cross-section data and nonlinear material response).
Added thermal expansion to generalized strains in simple cross-section. Simplified code.
