I've added LinearOperator and aslinearoperator() to SVN:
aslinearoperator() accepts all of the things that made sense for the
'A' parameter of the iterative solvers (dense matrices, sparse
matrices, and objects with .shape and .matvec() attributes)
Take a look at it and let me know if you see any issues.
I included a dtype attribute in LinearOperator to take the place of
the xtype parameter of the iterative solvers.
Next on the TODO list:
Update iterative solvers to use aslinearoperator()/LinearOperator
Replace A.psolve with precond=M parameter (where M is also a LinearOperator)
Clean up MINRES translation:
Generalize the stopping criteria used by the iterative solvers
