Detailed Description

Problem generator shear wave test with Lagrangian particles.

PURPOSE: Problem generator shear wave test with Lagrangian particles. Must work in 3D, and the wavevector is in x2 direction. Particles can be initialized either with uniform density or with density profile same as the gas. SHEARING_BOX must be turned on, FARGO is optional.
