[DEV-0003] Fixed minor issues, created Statistics, changed Expenses to Budgeting, added changelog

0.0.3
NEW
- Added CHANGELOG.txt to map out changes
MAIN
- Added versioning line to list out application name and version
BUDGET
- lists out current budgets or notes that there are no budgets
prior
to inputting.
INCOME
- thought up logic for other forms of income
- did a basic set up for inputting multiple incomes
CHANGES
- Refactored EXPENSES to BUDGET due to implementation more like
setting
thresholds
- minor consistancy changes
- set up so that MAIN runs functions from each class so all is
centralized
- changed some wording and formatting to make it a little more
user friendly
BUDGET <- EXPENSES
- changed variable names
- Allow for input of decimal percentages
STATISTICS
- got rid of useless variables for now since the plan is to
calculate
without inputting values into stats, but directly from other
classes
- STATISTICS is now planned to be the central hub to print out
calculations
MAIN
- set up precaution to running stats without any budgeting (for now
since stats only has calculate by budgets given);
TODO
- create a format for (TEXTFile/CSV) for loading and saving
- create logic to parse SAVEFILE when loading
- create logic to save SAVEFILE (on exit? or changing between
"HUBs")
- create console for this project to have the console clear each
time
choices are available.
