This major overhaul of the IllinoisGRMHD thorn uses GRHayL to implement its original features. In addition, it introduces entropy evolution, tabulated equation of state, and piecewise polytrope support. All con2prim routines provided by GRHayL are also automatically supported by the thorn, with control of this behavior governed by the GRHayLib thorn.
