2f86cdc712 STYLE: more consistent use of dimensioned Zero
- when constructing dimensioned fields that are to be zero-initialized,
  it is preferrable to use a form such as

      dimensionedScalar(dims, Zero)
      dimensionedVector(dims, Zero)

  rather than

      dimensionedScalar("0", dims, 0)
      dimensionedVector("zero", dims, vector::zero)

  This reduces clutter and also avoids any suggestion that the name of
  the dimensioned quantity has any influence on the field's name.

  An even shorter version is possible. Eg,

      dimensionedScalar(dims)

  but reduces the clarity of meaning.

- NB: UniformDimensionedField is an exception to these style changes
  since it does use the name of the dimensioned type (instead of the
  regIOobject).

56bfc75949 Rationalize the "pos" function
"pos" now returns 1 if the argument is greater than 0, otherwise it returns 0.
This is consistent with the common mathematical definition of the "pos" function:

https://en.wikipedia.org/wiki/Sign_(mathematics)

However the previous implementation in which 1 was also returned for a 0
argument is useful in many situations so the "pos0" has been added which returns
1 if the argument is greater or equal to 0.  Additionally the "neg0" has been
added which returns 1 if if the argument is less than or equal to 0.

9d1eb05bdc VoF solvers: New interfaceCompressionFvPatchScalarField BC and additional shear compression
Provides the additional compression necessary to ensure interface integrity
adjacent to a boundary at a low angle of incidence to the interface.  This is
particularly important when simulating planing hulls.

86dc955605 interFoam family of solvers: Improved Crank-Nicolson implementation
Fewer limiter iterations are now required to obtain sufficient boundedness and
restart is more consistent.

b167c95f19 compressibleInterFoam: Completed LTS and semi-implicit MULES support
Now the interFoam and compressibleInterFoam families of solvers use the same
alphaEqn formulation and supporting all of the MULES options without
code-duplication.

The semi-implicit MULES support allows running with significantly larger
time-steps but this does reduce the interface sharpness.
