Author: murilov
Date: 2010-06-03 16:25:02 EDT (Thu, 03 Jun 2010)
New Revision: 62417
URL: http://svn.boost.org/trac/boost/changeset/62417

Log:
Changed the file utils.hpp to bit_utils.hpp
Changed the name of is_bit_set template to test_bit
Deleted the static_bit_reversal_base. Now using integral_constant from Type Traits library.
