ExportXml
------------------------------------------------------------
Export reports to an Xml format.

This sample shows how you can implement a custom export filter
and export reports to Xml.

Custom export filters derive from the C1.Win.C1Report.ExportFilter 
base class and override methods to render sections and fields. This
sample implements an XmlFilter class that renders report elements
into an XmlWriter.

Once you have a filter, use the RenderToFilter method to render 
the report into the filter.

Export filters are flexible and powerful. All the C1Report built-in 
export filters (Pdf, Html, Rtf, etc) use this approach.
