removeIsomorphs -- removes all isomorphs from a list of graphs

Description

This method returns the sublist of $L$ giving all non-isomorphic graphs with selection based on which comes first in $L$. The format of the graph is retained.

i1 : R = QQ[a..f];
 
i2 : G = {"EhEG", cycle R, completeGraph R, graph {a*d, d*b, b*e, e*c, c*f, f*a}};
 
i3 : removeIsomorphs G

o3 = {EhEG, Graph{"edges" => {{a, b}, {a, c}, {a, d}, {a, e}, {a, f}, {b, c},
                  "ring" => R
                  "vertices" => {a, b, c, d, e, f}
     ------------------------------------------------------------------------
     {b, d}, {b, e}, {b, f}, {c, d}, {c, e}, {c, f}, {d, e}, {d, f}, {e,
