spc_moments_wall Subroutine

public subroutine spc_moments_wall(me, state, bcBuffer, globBC, levelDesc, tree, nSize, iLevel, sim_time, neigh, layout, fieldProp, varPos, nScalars, varSys, derVarPos, physics, iField, mixture)

Moment based wall boundary condition from Sam Bennent PhD thesis "A Lattice Boltzmann Model for Diffusion of Binary Gas Mixtures"

This subroutine's interface must match the abstract interface definition boundaryRoutine in bc/mus_bc_header_module.f90 in order to be callable via fnct function pointer.
