Milestone:  To Be Determined                          |   Component:  range         
  Version:  Boost 1.49.0                              |    Severity:  Not Applicable
 Keywords:  range mfc map_keys adaptor                |  
------------------------------------------------------+---------------------
 While the existing MFC/ATL headers mostly work with the range algorithms
 and adaptors, using map_keys and map_values fails due to the return type
 of CMap<>::CPair etc. This provides a specialization of the select_first,
 select_second_const, and select_second_mutable template classes which
 allows CMap<> and CMapStringToString to work with the map_keys and
 map_values range adaptors. Due to the layout of everything, there did not
 seem to be an applicable place to insert this code, therefore I created a
 new mfc_map.hpp file under adaptors. While I am uncertain whether this is
 fit for the library itself, perhaps it will be of use to others who happen
 across this.
