As part of a patch fix for:

http://bugzilla.ecoinformatics.org/show_bug.cgi?id=2469

I've changed DocumentImpl.java in three locations:

buildIndex()
traverseParents()
updatePathIndex()

This patch modifies updatePathIndex() by changing the pathsFound input
parameter to a HashMap from a Vector. The HashMap stores PathIndexEntry
objects that represent each row to be inserted into the xml_path_index table.
The HashMap prevents nodeids from the current node from being offset with
the data from adjacent nodes under certain circumstances, which was happening
while a Vector was being used to store paths found for indexing. See the next
two patches for more info.
