The FusionRing and its methods contain nearly complete information about the underlying modular tensor category. However information is lost about the associator, and this is captured by the F-matrix or 6j symbols. This ticket adds a method to compute the F-matrices.

This may be tested on the rank <=4 examples in the paper of Rowell, Stong and Wang (arXiv:0712.1377). It is able to compute F-matrices for these examples except the last one, G2 at level 2.
