User ready version
User ready version

* Added improved comments that explain the syntax of the program
* Adjusted function names to be more discernible from variable names
* Added several functions to calculate, organize, and write the budget
* The budget is now saved as a text file named by the user
* Removed several lines of code from that were left over from the program's predecessor
* Renamed variables to make more sense
* Removed extraneous code

**MISSING FROM THIS VERSION**
* There is no error checking, so if a user types in a string where an integer is needed, the program will fail
