Solver checks

The mismatch is what is left when the stored solution is put back into the heat equation with fourth-order differences, as a heating rate. It is largest beside the wires, which the grid cannot resolve; show it on the slice with the Mismatch switch.

A zip of CSV files: every cell's temperature at the start of every solver step, and the heat put into it during the step, with the grid, the materials, the steps and a README that says how to read them and redo the steps.
