Implement Lax-Friedrichs for Euler's equations #16

Closed MatthewGrim closed 7 years ago

This issue documents the implementation of a simple Lax Friedrichs scheme for Euler's equations. The aim is simply to go back to the basic methods and get a better understanding of artificial viscosity.

In the end I ended up implementing Lax Wendroff - this works for Sod1 but is failing for other sod problems. I can't say I know why yet.
