Get the descrition of this specific processor. This function must be overwritten by a subclass.
Implements EMAN::Processor. Definition at line 6135 of file processor.h. 06136 {
06137 return "Replace a source image with a lumpy S-curve used for alignment testing";
06138 }

Get the processor's name. Each processor is identified by a unique name.
Implements EMAN::Processor. Definition at line 6130 of file processor.h. 06131 {

To process an image in-place. For those processors which can only be processed out-of-place, override this function to just print out some error message to remind user call the out-of-place version.
