That corresponds to an operator splitting s

Dear all,
the "Constraints on Degrees of Freedom" module introduces several
approaches to deal with constraints.
I implemented the "second" approach, that is, distributing the constraints
on the fly when assembling the linear system using the
constraints.distribute_local_to_global() function.
