Change the return type of sTgcDigitMaker helper functions to StatusCode
Helper functions that read parameters from txt files print out fatal messages upon failure. It was suggested in MR !46903 (merged) to edit these functions to return StatusCode. Additional changes are: deletion of an unused function efficiencyCheck(const int) and suppression of some messages. This function efficiencyCheck, in addition to be unused, has a bug that can potentially cause confusion.
