Schroedinger functional stuff.

Compute correlation functions between axial current or pseudescalar density and boundary fields using Schroedinger BC.

Also computed, on demand, are correlation functions between both boundaries with zero, one (std::vector current) and two (axial current or pseudoscalar density) insertions in the bulk. These currents are controlled by the ZVfactP and ZAfactP boolean flags.

Compute quark propagators by using the qprop SystemSolver. The initial guess for the inverter is zero.

The results are written to the xml file.

For further details see the comments in the dependent subroutines.

Parameters

state	gauge field state ( Read )
qprop	propagator solver ( Read )
phases	object holds list of momenta and Fourier phases ( Read )
ZVfactP	flag for doing Z_V measurements ( Read )
ZAfactP	flag for doing Z_A measurements ( Read )
x0	time slices with axial current insertions ( Read )
y0	time slices with axial current insertions ( Read )
xml	xml file object ( Write )
xml_group	std::string used for writing xml data ( Read )
