array is a sequence

[akrzemi1]

According to docs of Boost.Test v3, a C-array is not recognized as a sequence, and cannot be used with sequence-based test assertions. I think it is an unjustified limitation.

Instead of requiring that type T should have member functions .begin(), .size(), use the approach taken by Boost.Foreach, and only require of ranges, that the following expressions are valid:

boost::begin(e), boost::end(e)

There is no need to require size(), one can always compute it from std::distance(begin(e), end(e)).
