I would like to solve a nonlinear parabolic pde system
of two variables u, v. Each in turn is a function of
(x,t). In future, I would like to extend such a thing
to (x, y, z, t). Please let me know how to do this, if
possible in Mathmematica.

The equations look like this:

a*u_t = b*u_xx + c*f(u,v)
d*v_t = e*v_xx + h*g(u,v)

-ll <= x <= ll
0 <= t <= 10

with boundary conditions: u_x(+/-ll, t), v_x(+/-ll,
