mod_symtaumat Module
Find the symmetry matrices DROT that act on t, tau
KREL=0: for real spherical harmonicsKREL=1: for relativistic represntation
The NSYM allowed symmetry operations are indicated by ISYMINDEX in the table ROTMAT.
For KREL=1, SYMUNITARY=T/F indicates unitary/antiunitary symmetry operation.
The routine determines first the Euler angles correponding to a symmetry operation. Reflections are decomposed into inversion + rotation for this reason
