 * waitForKeyElements.js (CoeJoder Fork) - https://github.com/CoeJoder/waitForKeyElements.js
 * 
 * A utility function for userscripts that detects and handles AJAXed content.
 *
 * Usage example:
 *
 *     function callback(domElement) {
 *         domElement.innerHTML = "This text inserted by waitForKeyElements().";
 *     }
 * 
 *     waitForKeyElements("div.comments", callback);
 *     // or
 *     waitForKeyElements(selectorFunction, callback);
 *
 * @param {(string|function)} selectorOrFunction - The selector string or function.
 * @param {function} callback - The callback function; takes a single DOM element as parameter.
 *                              If returns true, element will be processed again on subsequent iterations.
 * @param {boolean} [waitOnce=true] - Whether to stop after the first elements are found.
 * @param {number} [interval=300] - The time (ms) to wait between iterations.
 * @param {number} [maxIntervals=-1] - The max number of intervals to run (negative number for unlimited).
