Description: 
 This function returns a pointer to the 
FrameSet encapsulated by a
Region. The base 
Frame is the Frame in which the box was originally defined, and the
current Frame is the Frame into which the Region is currently mapped (i.e. it will be
the same as the Frame returned by 
astGetRegionFrame).  
Synopsis 
 AstFrame
astGetRegionFrameSet(
AstRegion this
)  
 Parameters: 
  this  
 Pointer to the Region.  
    Returned Value 
  astGetRegionFrameSet()
                                                                                       
                                                                                       
 A pointer to a deep copy of the FrameSet represented by the Region. Using this
pointer to modify the FrameSet will have no effect on the Region.
