- support non-uniform scaling, prescaling and cartesian coordinate
transformations.
Eg, stretch in one direction and then rotate
```
prescale (1.5 1 1);
transform
{
origin (0 0 0);
rotation
{
type axisAngle;
axis (0 0 1);
angle 45;
}
}
```
- support "transformed" versions of blockMesh vertices, topology.
With the additional of transformations etc, a simplistic application
of a single scale parameter is no longer sufficient.
new: blMesh.vertices(true);
old: blMesh.vertices() * blMesh.scaleFactor();
new: blMesh.topology(true);
old: N/A
- add individual edge access for blockDescriptor.
Saves copying and duplicate calculations.
- handle '(block face)' specification for curved faces,
which is ok for external block faces, but likely somewhat
questionable if used for internal block faces.
