	Some DOM object properties and method:
	P R O P E R T Y					D E S C R I P T I O N
	nodeName						name of the node
	nodeValue						value of node (only applicable to text nodes)
	nodeType						type of node - see below
	parentNode						parent, if one exists
	childNodes						list (array) of child nodes
	firstChild						first child
	lastChild						last child
	previousSibling					previous sibling
	nextSibling						next sibling
	attributes						list of attributes of an element
	ownerDocument					document containing the element
	
	M E T H O D S					D E S C R I P T I O N
	appendChild()					append a node to node's list of child nodes.
	createElement					create new HTML element, but doesn't "attach" it to the DOM hierarchy.
	createTextNode()				create new text node, but doesn't "attach" it to the DOM hierarchy.
	geElementById()					get a node from the hierarchy
	insertBefore(child1,child2)		inserts the node child1 as a new child node before node child2 
	removeChild()					remove child node
	replaceChild(child1,child2)		replace node child2 by node child1
