+ * 14 Apr 2012 - (mtc) Added support for boost::hash
+ * 28 Dec 2010 - (mtc) Added cbegin and cend (and crbegin and crend) for C++Ox compatibility.
+ * 10 Mar 2010 - (mtc) fill method added, matching resolution of the standard library working group.

  * 29 Jan 2004 - c_array() added, BOOST_NO_PRIVATE_IN_AGGREGATE removed (Nico Josuttis)
  * 23 Aug 2002 - fix for Non-MSVC compilers combined with MSVC libraries.
