Output Parameter
Loop over batch of elements (e):
Loop over quadrature points (q):
Make u_q and gradU_q (loops over fields,Nb,Ncomp) and x_q
Call f_0 and f_1
Loop over element vector entries (f,fc --> i):
elemVec[i] += \psi^{fc}_f(q) f0_{fc}(u, \nabla u) + \nabla\psi^{fc}_f(q) \cdot f1_{fc,df}(u, \nabla u)
