Detailed Description

the stabilized biconjugate inverter

It inverts mul_Q(psi_out,psi_in,U,coeff) iteratively

Parameters:

	psi_out	the output field passed by reference
	psi_in	the input field passed by reference
	U	the gauge field to be passed to mul_Q
	coeff	the gauge parameters to be passed to mul_Q
	absolute_precision	the target absolute precision
	relative_precision	the target relative precision
	max_steps	the maximum number of steps

Example:

    gauge_field U(lattice,nc);
    fermi_field psi(lattice,nc);
    fermi_field chi(lattice,nc);
    coefficinets coeff;
    coeff["kappa"]=1.12;
    U.load("myfield");
    psi.load("myfield_psi");
    default_fermi_inverter=BiCGStab::inverter<fermi_field,gauge_field>;
    default_fermi_action=FermiCloverActionSlow::mul_Q;
    mul_invQ(chi,psi,U,coeff);
    chi.save("myfield_chi");
    

Note that mul_invQ(chi,psi,U,coeff) reads
