This is the Matlab version of GAMERA MHD Solver, Authors B. Zhang, J. Lyon, K. Sorathia, Aug. 2018

MAIN FEATURES:
     physics:
        1. Single-fluid, ideal MHD equations (ideal Ohm's law)
        2. Plasma energy equation (semi-conservative)
        3. Semi-relativistic (Boris/Alfven) correction (disabled default)
     numerics:
        1. Finite-volume method
        2. Non-orthogonal Curvilinear grids
        3. Constraint transport for magnetic flux
        4. second-order predictor/corrector in time
        5. seventh-/eighth-order spatial reconstruction
        6. PDM limiter with non-clipping option
        7. Gas-kinetic flux functions
        8. Background magnetic field splitting
