Class Description

 TKeyXML is represents one block of data in TXMLFile
 Normally this block corresponds to data of single object like histogram,
 TObjArray and so on.
________________________________________________________________________

 default constructor

 Creates TKeyXML and convert obj data to xml structures

 Creates TKeyXML and convert obj data to xml structures

 Creates TKeyXML and takes ownership over xml node, from which object can be restored

 TKeyXML destructor

 Delete key from current directory
 Note: TKeyXML object is not deleted. You still have to call "delete key"

  convert object to xml structure and keep this structure in key

 To read an object from the file.
 The object associated to this key is read from the file into memory.
 Before invoking this function, obj has been created via the
 default constructor.

 read object derived from TObject class, from key
 if it is not TObject or in case of error, return 0

 read object of any type

 read object from key and cast to expected class

 return pointer on TXMLEngine object, used for xml conversion
