 * @param {EventTarget} element The element that you wish to autoreplace text in.
 * @param {Array} arr The array of options arrays. Each array element should be an array, with its first element being a string to input, and the second being a RegExp or array of RegExps that it will replace 
 * @example <caption>Replaces any match of the regex's /Hello/gi or /example/g with the string "World" in the element with id=input</caption>
 * autoReplace(document.getElementById("input"), [
 *  ["World", [/Hello/gi, /example/g]]
 * ]);
