### Version 1 ###

#### PROGRAM NOTES:  ADDED TERMINAL FORMATTING THAT ONLY WORKS ON UNIX SYSTEMS!

### Ideas for version 2:
### Create GUI including buttons for all functions using the Tkinter module that
### is part of Python's standard library.
### Fully working directory system, multiple turtles, etc.

## Possible alternative directions that could of been taken/would like to
## explore further:
## Depreciate the use of global values by using a dictionary, this will allow
## for references .__doc__ docstrings for an interactive help function.
## Regular expressions and various other more advanced string tools to
## manipulate file input.
## Also: the ability to take different forms of input with different delimiters.
