printWeylModuleElement -- display a Weyl-module element as a linear combination of tableaux

Usage:

printWeylModuleElement(v, W)
Inputs:
- v, a vector, a vector in a Weyl module W
- W, a module, a Weyl module returned by weylModule

Description

The Weyl analogue of printSchurModuleElement: prints v as $\sum_T c_T \cdot T$ over Weyl-semistandard WeylFillings $T$ in the cached basis of W.

i1 : W = weylModule({2,1}, QQ^3);

i2 : v = sum(numgens W, i -> (i+1) * W_i);
