/**
* This handles a variety of flavors of xml documents (e.g., thredds query capability, thredds
* catalogs, idv menus) to create data choosers from. It provides a combobox to enter urls to xml
* documents. It retrieves the xml and creates a {@link XmlHandler} based on the type of xml.
* Currently this class handles two types of xml: Thredds catalog and Web Map Server (WMS)
* capability documents. The XmlHandler does most of the work.
*
* <p>This class maintains the different xml docs the user has gone to coupled with the XmlHandler
* for each doc. It uses this list to support navigating back and forth through the history of
* documents.
