	*
	* (Boolean) margin - Should the margin of the element be included in the calculations? True by default.
	* (Boolean) border - Should the border of the element be included in the calculations? False by default. 
	* (Boolean) padding - Should the padding of the element be included in the calculations? False by default. 
	* (Boolean) 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.
	* (Boolean) lite - When true it will use the offsetLite method instead of the full-blown, slower offset method. False by default.
	*                  Only use this when margins, borders and padding calculations don't matter.
	* (HTML Element) relativeTo - This should be a parent of the element and should have position (like absolute or relative).
	*                             It will retreive the offset relative to this parent element. By default it is the body element.
	*
	* Also an object can be passed as the second paramater to
	* catch the value of the return and continue the chain.
	*
	* For accurate calculations make sure to use pixel values for margins, borders and padding.
	* 
	* Known issues:
	*  - Issue: A div positioned relative or static without any content before it and its parent will report an offsetTop of 0 in Safari
	*    Workaround: Place content before the relative div ... and set height and width to 0 and overflow to hidden

	* @example $("#testdiv").offset()
