The main task of this method is to apply constraints (of various forms implemented in various methods). Combinations of different types need to be considered: 1) homogeneous, 2) inhomogeneous, 3) linear, 4) nonlinear. Combinations of different methods need to be considered: 1) penalty, 2) multiplier. On exit, the global stiffness matrix should be updated, the global residual vector should be updated.

Reimplemented from Integrator.
