ENH: Adding option to thermalBaffle to be used as external/internal baffle

Browse Source 
Now the thermal baffle can be extrapolated from a patch which is
  coupled to the bottom patch of the solid region.

  The user can set the T bc on the 'top' patch of the solid.

  The new keyword is 'internal' and its default is true. Check new
  tutorial for an example:

The primary region creates the baffle region and evolves its energy
equation either:
- 1-D, normal to each patch face
- 2-D, normal and tangential components
- 3-D, normal and tangential components
The thermodynamic properties of the baffle material are specified via
dictionary entries on the master patch.
The underlying polyPatch on the primary region needs to be defined
as a complete mappedWall. i.e:
\verbatim
type mappedWall;
sampleMode nearestPatchFace;
samplePatch <patchName>;
sampleRegion <regionName>;
coupleGroup <coupleGroupName>;
\endverbatim
The /keyword{internal} is true when the thermal baffle is used on internal
faces and the baffle is coupled on both sides (bottom and top).
If this baffle is used on a patch set internal = false. By default is
true.
