WIP on tests.

Merged Assembly_test.h and Compliant_test.cpp to Assembly_test.cpp

Fixed a bug in DiagonalCompliance and UniformCompliance: matK must be computed in all cases, because it is used to compute the compliance forces.

Changed values in BilinearConstraint examples to make them more clear.
