- Removes need for additional call to info in the main solver code

     sensible enthalpy thermo packages

- Enthalpy source term now retrieved from the chemistry model (scaled by
  kappa for the PaSR model)

- Added chemical enthalpy access function to top level api.
- Re-worked source term for enthalpy equation(s) in chemistry model, and
- Re-worked heat release calculation

STYLE: Using worded dimensions instead of dimensionSet(...)

Each collocated set of coupled points has a single master assigned to it.
However when doing mergePoints on a patch the master does not have to be
on the patch. So now it returns mesh point labels, not patch point labels.

default values for motion state.

- moved sources from fireFoam solver into the thermophysicalModels library
- code clean-up

- removed support for total enthalpy
- much cleaner/improved code for transfer terms

For non-premixed combustion using sensible enthalpy.

STYLE: drop surface extraction from foamToStarMesh

- retain surfZone names when writing surfaces
- remove surface extraction/writing from meshWriter since it now
  duplicates what the meshedSurface class can do.

orientation != I at start.

Being more careful with when using directions relative to the absolute
axes or the direction of something relative to its initial direction.

Renaming p0, v0 to pInitial, vInitial to be clearer.

fixedOrientation constraint does not need a reference orientation, as
it is not to move at all, relative to any orientation, so the
Cartesian axes are fine.
