New array crystallite_symmetryID(i,g,e) is now filled during initialization run with 1 for bcc and fcc phase and 2 for hexagonal phase. The values are needed for misorientation calculations to apply the correct symmetry operators for cubic and hexagonal phases.

(output) grainrotation
it gives the deviation from the initial grain orientation
in axis-angle representation with the angle in degrees.

changed internal representation of orientation and misorientation from euler angles to quaternions (this should also fix some bugs in the math_misorientation subroutine). includes a couple of new functions in math.f90 and some changes in crystallite.f90.
...
beware that crystallite output "orientation" now by default returns the orientation as quaternion. if you want euler angles instead, you have to add "eulerangles" as a crystallite output in your material.config file (see material.config template).
for input of orientations in the texture block of the material.config you still have to specify the rotation in terms of euler angles, quaternions are not yet supported for input.
