Detailed Description

template<typename T>
class Chroma::FermAct5DQprop< T >

This routine is actually generic to all non-preconditioned (not red/black) fermions

Compute the lattice fermion for a generic non-red/black fermion using the source in "chi" - so, the source can be of any desired form. The result will appear in "psi", which on input contains an initial guess for the solution.
