Jacobian elliptic functions

Calculates the Jacobian elliptic functions of parameter m between 0 and 1, and real u.

Parameters:	m, u Parameters
Returns:	sn, cn, dn, ph The returned functions: sn(u|m), cn(u|m), dn(u|m) The value ph is such that if u = ellik(ph, m), then sn(u|m) = sin(ph) and cn(u|m) = cos(ph).
