Detailed Description

staggared quark propagator

On a (2n) dimensional lattice this makes 3*(2^n) sources at the vertices of the hypercube at the origin of the lattice and inverts the Staggered/Asqtad action on them.

Example:

/// mdp_gauge U(lattice,nc);
/// staggered_propagator S(lattice,nc);
/// mdp_site x(lattice);
/// mdp_site y(lattice);
/// coefficients coeff;
/// coeff["mass"]=1.0;
/// generate(S,U,coeff);
/// for(int i=0; i<(int) pow(2,lattice.ndim); i++) {
///    x=binary2versor(a);
///    cout << "source at:" << x << "\nprop:\n"; 
///    forallsites(y) cout << S(x,a) << endl;
/// }
///
