// 0.6 - Added a warning when submit after option is checked. It will only warn once.
// This script will hide the instructions but you can click on the instruction text to show the full
// instructions again. You will see 2 buttons at the top of the receipts for easy access. If the receipts
// are different then click on the first button. If they are the same then click on the second button.
// Once you push a button it will fill in the bottom radio buttons and submit the hit if you checked the
// checkbox called submit after. By default it will not submit after so you have to press the submit button
// or press enter after the submit button gets focused. You can also use keyboard shortcuts to make it easier.
// Keyboard shortcuts follow the submit after setting so be careful. Pressing n or 1 will select
// the no option. Pressing y or 2 will select the yes option. Then you can press enter to submit the hit or
// click the submit button if the submit after option is off.
//
// 0.5 - Added a setting checkbox to submit after button pressed. It is turned off by default and saved.
// 0.4 - Added buttons at top. Allows keypad numbers to work. Hides the instructions at top.
