#8 Various Mondrian Compatibility Fixes

[Will Gorman]

Attached are three file changes that were necessary for compatibility with the latest version of Mondrian (3.0.1 and newer):

MondrianModel.java
These changes address the removal of deprecated methods from Mondrian's API

XMLA_Member.java
This change fixes a bug with JPivot not displaying drill down's correctly for parent child hierarchies when talking to Mondrian's XMLA driver

MondrianOlapModelTag.java
This change fixes a bug where a VFS url is used to access Mondrian's schema that java.net.URL isn't aware of.
