sys - the section symmetries
stratum - the stratum value in the label that we are assigning symmetries for
size - the number of dofs for points in the stratum of the label
minOrient - the smallest orientation for a point in this stratum
maxOrient - one greater than the largest orientation for a ppoint in this stratum (i.e., orientations are in the range [minOrient, maxOrient))
mode - how sym should copy the perms and rots arrays
perms - NULL if there are no permutations, or (maxOrient - minOrient) permutations, one for each orientation. A NULL permutation is the identity + rots - NULL if there are no rotations, or (maxOrient - minOrient) sets of rotations, one for each orientation. A NULL set of orientations is the identity
