Jupiter lags when I/O takes place

[GoogleCodeExporter]

I have debugged and Jupiter is doing a lot of unnecessary XML parsing.  The
reading often is a flaw in Jupiter's model and must be addressed.

I suspect Jupiter also shows signs of slower I/O due to JAXB.  JAXB seems
to have the poorest performance and even though it is easy to use I think
it needs to be taken out.  I am opting to use StAX.

Some extra checks will improve Jupiter's performance a little bit by
preventing some unnecessary file I/O.  These initial fixes will appear in
Jupiter 3.4.0.  StAX should also make its appearance in Jupiter 3.4.0.

Actual major changes to the model will be in Jupiter 3.4.1.

I am deferring model changes to the next release of Jupiter.

StAX appears in Jupiter 3.4.1 not 3.4.0.  This was a typo.

Closing issue because it has been open a while and it seems that performance 
has improved since the removal 
of JAXB.
