Detailed Description

2D2V Kelvin-Helmholtz Instability using the Maxwellians as the initial condition for the distributions

This is meant to take the fluid equilibrium (see Vogman Pop 2020 and PoP 2019) and convert these to Maxwellian distribution functions for the kinetic model, instead of using the the nonlinear ODE of Poisson's equation approach to find a kinetic equilibrium from them as shown in Vogman PoP 2019

Functionally, this version should not be a real equilibrium for the kinetic model.
