GMRES now supports preconditioning #29

Closed loiseaujc closed 1 year ago

loiseaujc commented 1 year ago

Added the possibility to pass a preconditioner to GMRES. INFO messages are raised for CG and BiCGSTAB. Although they comply with the extend interface for linear solvers, preconditioning is not supported yet for these and any preconditioner passed to these will be ignored.
