Detailed Description

LagrangianContactMechanics strategy.

Contact mechanics with face-centered lagrangian multipliers

dofLabel: 0 = displacement, x-component dofLabel: 1 = displacement, y-component dofLabel: 2 = displacement, z-component dofLabel: 3 = pressure

Ingredients:

1. F-points displacement (0,1,2), C-points pressure (3)
2. F-points smoother: AMG, single V-cycle, separate displacemente components
3. C-points coarse-grid/Schur complement solver: boomer AMG
4. Global smoother: none

Todo:

: (Sergey) I changed this from contiguous block setup to an equivalent marker array setup to make it a little easier (avoid passing DofManager, etc.). Will need to come up with a way to support both ways equally well. Maybe pass block offsets as constructor input.
