    ENH: timeControl: limit any timestep change if deltaTCoeff enabled.

    ENH: setTimeStep: have timeStart, timeEnd controls on time step adjustment.

    Also added smoothly varying time step change (through optional deltaTCoeff)

- Requires (1L << N) instead of (1 << N), otherwise it overflows
  and the result is zero.

Adds overset discretisation to selected physics:
- diffusion : overLaplacianDyMFoam
- incompressible steady : overSimpleFoam
- incompressible transient : overPimpleDyMFoam
- compressible transient: overRhoPimpleDyMFoam
- two-phase VOF: overInterDyMFoam

The overset method chosen is a parallel, fully implicit implementation
whereby the interpolation (from donor to acceptor) is inserted as an
adapted discretisation on the donor cells, such that the resulting matrix
can be solved using the standard linear solvers.

Above solvers come with a set of tutorials, showing how to create and set-up
simple simulations from scratch.

- this should not have been there in the first place

- user-selectable format (vtk or vtu, ascii or binary)
- dictionary syntax closer to ensightWrite
- tutorial example in windAroundBuildings

- eliminates the PtrList requirement (more flexible)

- eliminates the PtrList requirement (more flexible)

COMP: use tmp intermediate for volPointInterpolation return value

- gcc 4.8.5 had some weird issue of otherwise not binding a const-ref.
  (in foamVtkInternalWriterTemplates.C)

- elminate the foamVtkFormatter operator() in favour of xmlAttr.
  Improves readability and the purpose is clearer.

- By definition, binary STL uses float (not double) when reading.
  The ascii STL should be the same. This reduces memory overhead when
  loading files. The older triSurface reader had float, the surfMesh
  reader had double, but now has float.

- Inconsistency in the STL merge-tolerances between triSurface reader,
  surfMesh reader and WM_SP vs WM_DP. Now use consistent tolerances
  conrresponding to 10,100 * doubleSMALL.

- Similar float/double code adjustments for TRI format since this is
  very similar to the STL reader and had a similar inconsistency between
  the triSurface and surfMesh version. The AC3D reader still uses
  double when reading, but this can be revisited in the future (and can
  then remove the stichTriangles method too).

- can avoid the intermediate point distance field in exchange for
  calculating a point subtraction twice.

Update pEq for close domains.

2)Adapting divU in TEqn.H for compressibleInterDyMFoam and compressibleInterFoam
3)Re-instated sixDoFRigidBodyDisplacement as patch for pointFields. It allows to use a different fvDynamincMesh type
independently of the BC's

- use proxy writer for triSurface writing

- these are compile-time constants and can be marked as such in C++11.

Modification on rhoPimpleFoam pEq's for handling rho thermo and incompressible EoS. Adding rho limiters if p is limited.
This is important when LTS stepping or large Co number is used.

Updating rhoBuoyantPimpleFoam to handle closed domain for rho thermo and incompressible Eos.
Consolidating chtMultiRegionSimpleFoam and chtMultiRegionFoam pEqs to use the same formulation as rhoBuoyantPimpleFoam and
rhoBuoyantSimpleFoam

- with the xml append format it is possible to write raw binary
  (instead of base64), but the writer becomes more complicated.
  Either needs two passes to create, or need to allocate a block
  of space for the header information (like VTK itself does) and
  write later.

    * internalWriter
    * patchWriter
    * surfaceMeshWriter
    * lagrangianWriter

 Also these special purpose ones:
    * foamVtkWriteSurfFields

ENH: noiseModels - updated parallel usage (no longer needs proc dirs) and apply input data validation

Revert "sixDoFRigidBodyDisplacementPointPatchVectorField, uncoupledSixDoFRigidBodyDisplacementPointPatchVectorField: removed"

This reverts commit 942338b0.

COMP: unitConversion - using M_PI instead of pi to avoid compiltion error due to pi not evaluating to a constexpr

- this shifts responsibility away from caller to the individual writers
  for knowing which file formats are supported and which file ending is
  appropriate. When the writer receives the output format request,
  it can elect to downgrade or otherwise adjust it to what it can
  actually manage (eg, legacy vs xml vs xml-append).

  But currently still just with legacy format backends.

- was generally somewhat fragile. The main problem stems from the fact
  that several interfaces may be attached to a boundary. No trivial
  means of solving this without too much work for a feature that is only
  "nice-to-have".
