Blockstructured Adaptive Mesh Refinement in object-oriented C++

## 2D Euler equations - Ramp

Problem description Results: 2 Levels 3 Levels

This well-know example has been inspired by studies of planar shock-waves being reflected from wedges. A self-similar flow with a triple-point between incident shock and reflecting wall occurs. This example uses time-dependent physical boundary conditions at the upper boundary.

## Initial / Boundary Conditions
