/*
 * WK Anki Mode
 *
 * Often I get tons of reviews piled up and I have to sift through tons and tons of items
 * that I know very well. It takes a long time to type answers in, and sometimes you
 * mistype things accidentally and get discouraged even more. Thus this script removes
 * the need to type answers and simply display them, and mark them as being correct
 * or wrong. It relies solely on one's ability to be honest with themselves and not cheat.
 *
 * Used the following scripts as a reference:
 * http://userscripts-mirror.org/scripts/review/184992
