Usage #1: setupRCStore(sym [,opts])
Setup CGC container for given symmetry,
with the data stored in directory specified by the
environmental variable $RC_STORE.
Usage #2: setupRCStore(sym,q1,q2 [,opts])
explicitely request to generate tensor product
decomposition q1*q2
Options
'npass',... number of passes through gCG data (3).
'dmax',... specify max. average multiplet dimension sqrt(d1*d2)
in tensor product decomposition (10*qlen).
'-a' generate all, yet compatible with dmax (by default,
multiplets with 2-digit qlabels are no longer used
in decomposition)
