Initial commit of pyclaw multilayer code
Working without source terms
Oscillatory wave tank problem working
Rename of oscillating wind script
Work on idealized wave family begun
Wave family example working
discontinuous shelf example working
Add jump shelf example
Add sloped shelf test case

This test case is working for eigen methods 1 and 2.  3 computes to the
end but blows up prior to that and 4 stops due to imaginary eigenvalues.
Add old shelf contour plot script
Shelf contour plotting is working
Add entropy violating tests
Modify script dry state for runnign
initial mods for rarefaction example
Initial plane wave example
Start of source restructure
Move source to specific paths
Oscillatory example now running and plotting
Simple wave tests now working
Jump shelf test working
