Detailed Description

Asqtad Staggered-Dirac operator.

This routine is specific to Staggered fermions!

+ This subroutine applies the matrix or (M M) to the vector E,E Psi,

{ ~ { M(U) . Psi if ISign = PLUS Chi = { { ~ + { M(U) . Psi if ISign = MINUS NEED TO THINK MORE ABOUT THE ISIGN HERE AS IS IT NOT REALLY NEEDED!!! FOR NOW JUST CALL THIS ROUTINE WITH A PLUS!!

Algorithm:

The kernel for Staggered fermions is + (M M) = 4m**2 - D D E EO OE
