transformPoints
Description
Transforms the mesh points in the polyMesh directory according to the
options:
-translate vector
Translates the points by the given vector,
-rotate (vector vector)
Rotates the points from the first vector to the second,
-scale vector
Scales the points by the given vector.
The any or all of the three options may be specified and are processed
in the above order.
With -rotateFields (in combination with -rotate) it will also
read & transform vector & tensor fields.
