Implements the Biconjugate gradient method (similar to running the conjugate gradient on the normal equations).

<P>
Notes: this method requires that one be apply to apply the transpose of the preconditioner and operator
as well as the operator and preconditioner.
Supports only left preconditioning
<P>
See <A HREF="../KSP/KSPCGNE.html#KSPCGNE">KSPCGNE</A> for code that EXACTLY runs the preconditioned conjugate gradient method on the
normal equations
