nestReplacements

nodeLists.nestReplacements(list)

Goes through each node in the list. [el1, el2, el3, ...] Finds the nodeList for that node in replacements. el1's nodeList might look like [el1, [el2]]. Replaces that element and any other elements in the node list with the nodelist itself. resulting in [ [el1, [el2]], el3, ...] If a replacement is not found, it was improperly added, so we add it as a deepChild.
