ENH: Several modifycations to avoid erroneuos rays to be shot
from wrong faces.

ENH: Updating tutorials and avoiding registration of the
coarse singleCellFvMesh

Adding solarLoad tutorial case simpleCarSolarPanel

ENH: Changes needed for the merge

Adding reflecting fluxes to Solar load radiation model.
Adding functionality to the boundary radiation models and new
place holder for basic wall types such as transparent, opaqueDiffusive,
opaqueReflective,etc.
Changing radiation wall models to run time selectable.
Adding multi-band capabilities to VF model and improving the set up
for using solar loads in VF and fvDOM radiation models.

Revert "Change boundaryRadiationProperties and boundaryRadiationPropertiesPatch to mesh object and changing tutorials accordingly"

This reverts commit 662f9242.

Note: functionality moved to feature-boundaryRadiationProperties branch

Change boundaryRadiationProperties and boundaryRadiationPropertiesPatch to mesh object and changing tutorials accordingly

BUG: removed executable permissions on flameSpreadWaterSuppressionPanel case files and foamy make/options

gas , pyrolysis and film regions using fireFoam

The radiative properties are now held in the radiationModel in the solid
region instead than in the solidThermo
