ENH: integration of lumpedPointMotion

Browse Source 
- This provides a mechanism for moving mesh patches based on external
  input (eg, from an external structures solver). The patch points are
  influenced by the position and rotation of the lumped points.

  BC:  lumpedPointDisplacementPointPatchVectorField

  Controlling mechanisms:
  - externalCoupler
    for coordinating the master/slave

  - lumpedPointMovement
    manages the patch-points motion, but also for extracting forces/moments

  - lumpedPointState
    represents the positions/rotations of the controlling points

  Utils:
  - lumpedPointZones
    diagnostic for visualizing the correspondence between controlling
    points and patch faces

  - lumpedPointMovement
    Test that the patch motion is as desired without invoking moveMesh.
    With the -slave option, return items from a precalculated table
    for the lumpedPointDisplacementPointPatchVectorField BC.
