Obtain PDE solution

[dvignon]

Running this code (from the documentation).
First, it seems that discrete_x = sol[x] and discrete_t = sol[t] do not work. After replacing with discrete_x = 0:0.1:1 and discrete_t = sol.t, I get the following error message:

ERROR: ArgumentError: u(t, x) is either an observed nor a state variable.

I think this might be related to #6

Could you check your version of MethodOfLines.jl with ]st -m MethodOfLines?
You probably need v0.5.0 or newer versions to make sol[x] and sol[u(t, x)] work.
You can update your installation with ]up MethodOfLines or import Pkg; Pkg.add("MethodOfLines").

Thank you so much. This now works. I ran the update command before posting but did not realize it was still stuck at 0.4.0.
