the first field, ID, is just for keeping a standard sequence and isn't
called from any web pages. The second ($docid) is a random field which is
called from a web page, which makes it harder (if not impossible) to
guess/hack. This makes it a bit more secure.
A note about the old docid #'s, my intention is to replace the old $docid
with one in the new format. And, since the random docid is based (partly) on
the time at which it was generated, there's not much chance of it being
duplicated.
