// CREDITS: This is a replacement for an original script by Wanikani user @Ethan.
// Ethan's script stopped working due to some Wanikani changes. The code below is
// 100% my own, but it closely replicates the functionality of Ethan's original script.
// HOTKEYS:
// "+" - Marks answer as 'correct'.
// "-" - Marks answer as 'incorrect'.
// "Escape" - Resets question, allowing you to retype.
// SEE SETTINGS BELOW.

//===================================================================
// Theory of operation:
// ====================
// Wanikani's normal process:
// 1) User clicks 'submit'
// a) Wanikani checks answer and updates screen with the result.
// b) If both reading and meaning have been answered, Wanikani immediately sends the result to the server. (<-- BAD!!)
// 2) User clicks 'submit' (or enter) again to move to the next question.
// a) Wanikani updates the screen to show the next question.
//
// Our modified process:
// 1) User clicks 'submit'
// a) We intercept the click, check the answer ourself, and update the screen.
// Wanikani's code is unaware of what we're doing.
// b) User now has the opportunity to modify their answer.
// 2) User clicks 'submit' (or enter) again to move to the next question.
// a) We intercept the click again.
// b) We reset the display back to pre-submitted state, so Wanikani's code won't be confused.
// c) We call Wanikani's normal 'submit' function, but we intercept the answer-checker function,
// so Wanikani will see whatever result the user requested.
// Wanikani's updates the screen with the result.
// d) Keep in mind, the user has clicked the 'submit' button twice, but Wanikani has only
// seen one click. So, we have to send a third hidden click so Wanikani will catch up to
// where the user thinks we are (i.e. 'next question').
// 3) We intercept the hidden click, and forward it to Wanikani's code.
// a) Wanikani updates the screen to show the next question.
