gfanTropicalLinearSpace -- equations of a tropical linear space from Plücker coordinates



This method takes Plücker coordinates for a linear subspace and computes the polynomials which define the corresponding tropical linear space. The output is a pair which contains both the defining polynomials and a string which describes which coordinate corresponds to which minor.
