Element	$nodeB

Wikimedia\Parsoid\Html2Wt\DOMDiff::doDOMDiff	(	Node	$baseParentNode,
		Node	$newParentNode )

TODO: Implement something more intelligent like http://gregory.cobena.free.fr/www/Publications/%5BICDE2002%5D%20XyDiff%20-%20published%20version.pdf, which uses hash signatures of subtrees to efficiently detect moves / wrapping.

Adds / updates a data-parsoid-diff structure with change information.

Returns true if subtree is changed, false otherwise.

TODO: Assume typical CSS white-space, so ignore ws diffs in non-pre content.

Parameters

Node	$baseParentNode
Node	$newParentNode

Wikimedia\Parsoid\Html2Wt\DOMDiff::treeEquals	(	Node	$nodeA,
		Node	$nodeB,

Test if two DOM nodes are equal.
