 * @param Object options A hash of options describing what should be included in the final calculations of the offset.
 *                       The options include:
 *                           margin: Should the margin of the element be included in the calculations? True by default. 
 *                                   If set to false the margin of the element is subtracted from the total offset.
 *                           border: Should the border of the element be included in the calculations? True by default.
 *                                   If set to false the border of the element is subtracted from the total offset.
 *                           padding: Should the padding of the element be included in the calculations? False by default.
 *                                    If set to true the padding of the element is added to the total offset.
 *                           scroll: Should the scroll offsets of the parent elements be included in the calculations? 
 *                                   True by default. When true, it adds the total scroll offsets of all parents to the 
 *                                   total offset and also adds two properties to the returned object, scrollTop and 
 *                                   scrollLeft. If set to false the scroll offsets of parent elements are ignored. 
 *                                   If scroll offsets are not needed, set to false to get a performance boost.
 * @param Object returnObject An object to store the return value in, so as not to break the chain. If passed in the 
 *                            chain will not be broken and the result will be assigned to this object.
