+// Currently, the unid is set at the beginning of the algorithm.  It is used by the code that establishes correlation
+// based on first rejecting// tracked revisions, then correlating paragraphs/tables.  It is requred for this algorithm
+// - after finding a correlated sequence in the document with rejected revisions, it uses the unid to find the same
+// paragraph in the document without rejected revisions, then sets the correlated sha1 hash in that document.
+//
+// But then when accepting tracked revisions, for certain paragraphs (where there are deleted paragraph marks) it is
+// going to lose the unids.  But this isn't a problem because when paragraph marks are deleted, the correlation is
+// definitely no longer possible.  Any paragraphs that are in a range of paragraphs that are coalesced can't be
+// correlated to paragraphs in the other document via their hash.  At that point we no longer care what their unids
+// are.
+//
+// But after that it is only used to reconstruct the tree.  It is also used in the debugging code that
+// prints the various correlated sequences and comparison units - this is display for debugging purposes only.

+// The key idea here is that a given paragraph will always have the same ancestors, and it doesn't matter whether the
+// content was deleted from the old document, inserted into the new document, or set as equal.  At this point, we
+// identify a paragraph as a sequential list of content atoms, terminated by a paragraph mark.  This entire list will
+// for a single paragraph, regardless of whether the paragraph is a child of the body, or if the paragraph is in a cell
+// in a table, or if the paragraph is in a text box.  The list of ancestors, from the paragraph to the root of the XML
+// tree will be the same for all content atoms in the paragraph.
+//
+// Therefore:
+//
+// Iterate through the list of content atoms backwards.  When the loop sees a paragraph mark, it gets the ancestor
