update rpn2_geoclaw, geoclaw_riemann_utils

1

Need to initialize wave components 4:5 to 0 for Boussinesq code to work properly, and also pass `meqn,mwaves` rather than `3,3` to `riemann_aug_JCP`. There will also be a geoclaw PR...

Add VC traffic (Python) and Hughes' model solvers

1

Recently I worked on a project to implement Hughes' pedestrian model in 1D via Clawpack. In the process, I also created a solver for VC traffic written in Python (since...

Inconsistent common block

2

While trying to setup a quad grid examples, I noticed that the common blocks here https://github.com/clawpack/riemann/blob/master/src/rpn2_euler_mapgrid.f90#L44 https://github.com/clawpack/riemann/blob/master/src/rpt2_euler_mapgrid.f90#L69 and here https://github.com/clawpack/riemann/blob/master/src/euler_roe_solver_mapgrid.f90#L11 differ. The last one has `gamma1` which is not present...

Running nose tests on a new AWS EC2 instance revealed this issue in `rpn2_layered_shallow_water.f90` lapack is required or at least the subroutine `dgesv` and any dependencies: https://github.com/clawpack/riemann/blob/3d89c52f0c6ae6ed4e5ac3102b457b1931a8b592/src/rpn2_layered_shallow_water.f90#L103

Some of the solvers have outdated comments stating copyright and listing versions. The latter is dealt with by git, and all code here falls under the license for Clawpack. So...
