#2 XMLA Session support

[Jaimie Birk]

Have a way to enable/create XMLA sessions. For a simple example of how XMLA sessions are created and used in SOAP messages, see

http://docs.openlinksw.com/virtuoso/xmlxmla.html

The "State Support" section.

Or, see the XMLA specification, the section called "Support for Statefulness in XML for Analysis"
