OpenCytoPreprocessing.r :
- an attempt made to suppress the output while parsing workspaces (through the use of sink(...) )
- refactored the code to insert a row into the gstbl tables after the parsing is done
- before parsing is done, a check is performed to see if there is already a row with the same name, if yes, do not continue with heavy lifting parsing
