Get the processor's name. Each processor is identified by a unique name.
Implements EMAN::Processor. Definition at line 6124 of file processor.h. References NAME. 06125 { 06126 return NAME; 06127 }

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.
