conser - computes polynomial conserved densities for systems of nonlinear evolution equations.

Calling Sequences
 conser(a,b,x,c,options)

Parameters
 a - list of equations
 b - list of functions
 x - the independent spatial variable
 c - list of total rank of conserved densities
 options - (optional) parameters controlling solutions

Options
 flux - Computes the density's corresponding flux.
 parameters=p - Declares any parameters used in a. p is a list of the parameters in a.
 weights=w - User inputs the weights of the functions and parameters. w is a list of the weights of the
             functions in b.
 weightx=n -user inputs weight x
 returnweights - returns the computed weights
