COMPLILING INSTRUCTIONS:
- Clone the repository onto your local machine.
- Add your Facile program (int a txt file) to the Facile folder. For information on the syntax of the Facile language, see below.
- Type "qmake -project", then "qmake", then "make". Then "./Facile" to run the graphical debugger. You will then be prompted for the input file name.
