This contains the runtime Univ Texas/Arlington XQPull implementation
as referred to in the paper "A Fully Pipelined XQuery Processor" by 
Fegaras, et al.

The implementation was copied from their site on 30 Aug 07 and was
checked into svn under the xqpull 3rdparty product.  It was not changed
except to move it into a package and some other things to make it
work in the plugin environment.

This code was copied from that plugin on 31 Aug, and it corresponds to
revision 2290.

It will be modified as necessary to support runtime execution of the 
osdm semantics.

The original code is copyright as follows:
