New Revision: 55004
URL: http://svn.boost.org/trac/boost/changeset/55004

Log:
Started rewriting numeric_adaptor a totally different way.
Added:
   sandbox/numeric_adaptor/boost/numeric_adaptor/cln_value_type.hpp   (contents, props changed)
   sandbox/numeric_adaptor/boost/numeric_adaptor/gmp_value_type.hpp   (contents, props changed)
