printSchurModuleElement -- display a Schur-module element as a linear combination of tableaux

Description

Interprets v as an element of M and prints it as a sum $\sum_T c_T \cdot T$ over semistandard fillings $T$ in the cached basis of M, with each T drawn via its net method.

i1 : M = schurModule({2,1}, QQ^3);
 
i2 : v = sum(numgens M, i -> (i+1) * M_i);
