slip

The old behaviour assumed that the no-slip value was zero.  This has
been extended to enable the user to supply a refValue - the value at
zero slip.

This was similar to the mixedFixedValueSlipFvPatchField behaviour in the
rhoCentralFoam library - now deprecated in favour of the templated
partialSlip version.

- STLpoint.H
- isoAdvection.C
- checkMesh/writeFields.C

STYLE: drop construct STLpoint(Istream&), since it doesn't make much sense

- No use case for reading via an OpenFOAM stream and tokenizer.
  Should always be parsing ASCII or reading binary directly.

BUG: Fixing issue 505 in GL. Initializing switchProcessor and keepParticle in CollidingParcel and MPPICParcel

Calculates the acoustic pressure based on Curle's analogy.

Curle's analogy is implemented as:

    \f[
        p' = 4 \frac{\pi}{c_0}\frac{\vec d}{|\vec d|^2}\frac{d(F)}{d(t)}
    \f]

where
    p'          | Curle's acoustic pressure [Pa] or [Pa (m3/rho)]
    c_0         | Reference speed of sound [m/s]
    \vec d      | Distance vector to observer locations [m]
    F           | Force [N] or [N (m3/rho)]

Feature lumped point motion

See merge request !120

- 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.

- Can be useful when investigating mesh topologies
