- Added helper classes to simplify the handling of the injector properties
- Added new reacting multiphase injection model variant

- also minor code style tweaks

     the updated explicit source functionality

- Updates to solver, equations, createFields and createExplicitSources

- deprecated:
  - timeActivatedExplicitSource (old base type)
  - timeActivatedExplicitCellSource
  - timeActivatedExplicitMulticomponentPointSource

- introduced timeActivatedExplicitSource
  - templated on primitive type - scalar, vector, tensor...
  - takes as input, either a cell set or list of points

dictionaries - redundant.

restraint data to the classes themselves to allow class specific data
to be reported.

Have weight=7 on cells to be refined and balance. Then after refinement
there will be perfect balancing. Similar for layer addition.

It now caters for
- all surfaces having fields
- no surfaces having fields
but not a combination of those.

This directly samples on a triSurface (instead of using the isosurface of
distance=0 method)

The global sum of (integer) weights for metis&scotch has to be within the
valid range of integers. For now just divided the input (scalar) weights
with the minimum before truncating to integer.

tabulated with moment vs angle, not stiffness vs angle.

Adding more constraint reporting.

Changed order of evaluation of while condition to make +iter first,
otherwise doesn't increment iter, reporting 0 iterations.

constrainedSixDoFRigidBodyDisplacement BC - no longer needed.

Adding report Switch to turn on reporting.

Renaming linearSphericalAngularSpring to sphericalAngularSpring and
getting a moment contribution from each axis.  Can supply a reference
orientation.

sampledTriSurfaceMesh adds sampling on points/triangles of a triSurface(mesh).
All values outside mesh are set to 0.

     reacting multi-phase level of cloud/parcel

- changes to createClouds.H
- updated tutorial cases to reflect changes

Legacy BC superceded by directionMixed.

constraints to dictionary.
