Revision: 13504
          http://swig.svn.sourceforge.net/swig/?rev=13504&view=rev
Author:   wsfulton
Date:     2012-08-04 20:24:22 +0000 (Sat, 04 Aug 2012)
Log Message:
-----------
Fix using declarations and templates. %template was putting the
instantiated template into the global namespace instead of the namespace
of the template definition. This fixes regression in swig-2.0.5 copying
the std::pair typemaps which occurs with a 'using std::pair'
declaration. This also fixes lots of other using declarations of
template problems (template forward declarations. combinations
using directives).
