This routine computes equilbrium from density and velocity This must comply with interface in mus_variable_module derive_FromMacro
This subroutine's interface must match the abstract interface definition derive_FromMacro in derived/mus_derVarPos_module.f90 in order to be callable via equilFromMacro function pointer.
