Generalized Thresholded Landweber method using RSF commands.

Requires: RSFROOT environment has to be specified, such that $RSFROOT/bin is the path to RSF commands. SLIM python modules: Steppers and MultiPipe Parameters: ForwardOper: list of strings containing complete definition of forward operator AdjointOper: list of strings containing complete definition of adjoint operator (For both above, each string has to be a complete RSF command working on the stdin and stdout.) lambdaMax: maximum lambda lambdaMin: minimum lambda lambdaN: number of steps in iteration from lambdaMax to lambdaMin InnerN: number of iterations for any lambda DataIn: RSF file with input data DataOut: RSF file for output data Keyword parameters (optional): TMPDIR: temporary directory (system default if not specified) VERBOSE: verbose if set to True Returns: 0 if successful, positive number otherwise Notes: The function generates a number of temporary files that will have to be cleaned manually if it is forced to stop before it finishes. Bugs: None so far, but keep trying. It is not fool-proof. So, you have to know what you are doing; i.e., how to use RSF.
