AMRClaw for 1d problems

The two-dimensional code can also be used for 1-dimensional problems, by setting num_cells[1] = 1 so there is only one cell in the y direction. Also set refinement_ratios_y = [1,1,1, …] so that refinement is not done in this direction.

In this case the code will automatically do sweeps only in the x-direction and not attempt to solve any Riemann problems in the y-direction, or transverse Riemann problems.

The output in the fort.q000N files will be suitable for plotting with the one-dimensional Python plotting tools, e.g. these files will list the number of cells in x but not in y.

This appears to still have bugs and is being worked on.
