Validation cases

So far, only the original Roe scheme has been implemented, so the validations are done with this scheme.
The first validation case is resolving the oblique shock over the wedge of course:

Mach 2.36 Flow over a 20° wedge (Inviscid flow)

The wedge angle and Mach number are chosen such that the shock angle becomes 45° according to the 1-D oblique shock analysis (κ=1.4). Since the domain is a square, it is seen that the shock extends from the tip of the wedge (the domain center) to the domain corners.
