3.1.0
    * Added support for nested schemas.
    * Added support for XPath resultListLocator, instead of requiring the use
      of 'getElementsByTagName'.
    * Improved support for DOM elements in DataSchema.XML when IE
      xmldoc.selectNodes(String) fails.
    * Field list is now optional for DataSchema.JSON.  If omitted, all response
      data is returned.
    * Fixed a bug in field resolution where null might be discovered along the
      resolution path.  Now exits gracefully rather than throwing an error.
