 * Handling of DOM objects will rely on DOM object identifiers (ID) with a few exceptions. 
 * The focus of a dom object is mostly centered around a single DOM object, 
 * We advise using utils.js in order to handle collections of DOM objects as utils.js implements various utilities and industry standard design patterns
