Accountant Program for #2205~

This program is to save me from being the accountant of our apartment...

Tutorial

• DON'T follow your instinct... If the program crushes, I won't be responsible :)
• To delete someone you accidentally added in the participants (or just misspelled), type that wrong name again and click DELETE.
• The default buyer on the second page will be the ones from your last entry, if any.
• Add-stuff page supports arithmetic expressions input.
• If you entered a wrong item (or wrong price anyway), delete it by adding its negative price. Haven't implemented delete yet...

(Unimportant) Tips

Instead of clicking buttons you can

• Use Enter to enter input
• Use Shift + Enter to proceed to the next page

TODO

Someone helps me with GUI maybe...? The background color is so ugly...
