/*
 *This script was created for Tampermonkey(Chrome)/Greasemonkey(Firefox)
 *The nested unordered lists that are generated gets a class applied to them by the name of naviSub<headerNumber> so that each level can be styled. (it is also used for the generating process to find the last suitable list)
 *By clicking on the yellow triforce symbols you can show/hide nested lists.
 *A magin/padding trick has been applied to all page content headers (this is normally only applied to h2 headers) so that when you go to a specific anchor, the header will also be displayed.

//Plus Features/////////////////////////////////////////////////////////////////////////////////////////////////////
//Enables the Navi Menu on all pages. You can set the required amount of headers for the Navi Menu to appear.
//Changes the Navi Menu title to "Navigation+" to indicate that the plus features are enabled.
//The Navi Menu width is dynamic so that it can become slightly wider if the list items doesn't fit.
//If a page displays 2 h1 headers at the top of the page, the header with the page name will be removed.
//Wraps a link around the game logo in the upper left so that it takes you to the specified games main page.
//The Triforce font doesn't have a % symbol, so it is replaced with "Percent" in headers. Ex: "Any%" to "AnyPercent" (DISABLED)
