KSPBICG
Implements the Biconjugate gradient method (similar to running the conjugate gradient on the normal equations).
Options Database Keys
see KSPSolve() -
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
See KSPCGNE for code that EXACTLY runs the preconditioned conjugate gradient method on the
normal equations
