Defined the 'Dao.NewParser.RxDelete' constructor of the 'Dao.NewParser.RxPrimitive' data type, which evaluates to 'Dao.NewParser.clearBuffer' in the 'Dao.NewParser.regexPrimToLexer' function. This allowed me to define the 'Dao.NewParser.rxClear' :: 'Dao.NewParser.Regex' function.  I have started debugging the 'Dao.NewParser.Parser'.
