Sided product superoperator in the spherical tensor basis set. Returns superoperators corresponding to right or left multiplication of a density matrix by a user-specified operator. Syntax:

                 A=p_superop(spin_system,opspec,side)

Arguments:

    opspec - Spinach operator specification described in Sections 2.1
             and 3.3 of the following paper:
                    http://dx.doi.org/10.1016/j.jmr.2010.11.008
    side   - 'left' or 'right' causes the function to return a product
             superoperator corresponding to a product from that side;
             'comm' or 'acomm' results in commutation and anticommuta-
             tion superoperator respectively.

Note: This is a very general function to which direct calls are not usually required -- please use the (much friendlier) operator() function.
