// IDsQueryColumnHandler
// =====================
//  This interface is used by the query result view to allow the form to replace
//  the contents of the form columns.
//
//  If the property name is property,{CLSID}, we CoCreateInstance the GUID
//  asking for the IDsQueryColumnHandler which we then call for each
//  string property we are going to place into the result view.
//
//  The handler only gets called when the results are being unpacked from
//  the server, subsequent filtering, sort etc of the view doesn't
//  invole this handler.
//
//  However perf should be considered when implementing this object.
