Add BOOST_CHECK_EQUAL_RANGE to UTF

[Marcus Lindblom <macke@…>]

The following works nicely. The user has to include begin/end themselves, but it makes checking collections so much easier.

define BOOST_CHECK_EQUAL_RANGE(L,R) BOOST_CHECK_EQUAL_COLLECTIONS(boost::begin(L), boost::end(L), boost::begin(R), boost::end(R))
}}}}

This doesn't work if the range is an expression.

New Boost.Test release supports different syntax:

BOOST_TEST(l==R,test_tools::lexicographic())

or

BOOST_TEST(l==R,test_tools::per_element())
