anki.js

/**
 * Generates `data/anki.tsv`, which is a list of kanji identical to the
 * order of appearance in the kanjive.txt list.
 * 
 * This works by first generating the kanjiVE.txt file, which is sorted
 * purely based on the appearance of elements, with the exception of the
 * order.txt kanji being injected artificially into the ordering
 * (essentially forces the kanji for numbers 1-10 at the start).
