Recreator – RPN Lists (Tagged)

The recreator is now complete and all of the initial set of commands (LET, PRINT, INPUT, and REM) are fully supported.  The repository has been tagged v0.6.1 to mark this milestone.  Some minor issues were also corrected for this commit including:

• Corrected an expected results for the recreated translator test #12 (INPUT tests).
• Reorganized the access functions in the recreator class.
• Renamed the recreator class is empty access function to output is empty so as not to be confused with the stack is empty function.
• Renamed the recreator class last access function to the more explicit output last character and removed the output string is empty check.
• Corrected some comment formatting and added some missing comments.
• Corrected formatting issues where spaces were incorrectly added instead of tab characters (problems are caused by QtCreator editor bugs where is doesn't always pay attention to the spacing/tab settings).
• Added some missing FLAG option comments (details below).

The next major step is to integrate the recreator with the GUI, but in order to do this, the program code of lines needs to be decoded into an RPN list of tokens for the recreator.  When a line is entered into the program, it will be recreated and the recreated text will replaced the entered text in the edit box.  Preferences will be added to control the formatting of the recreated output, for example, if spaces should be added around operators, after commas, etc.  The FLAG option comments show where checks for these options will be.
