The following tests both compile after I updated two_bit_color_map.hpp to
use SFINAE on property_traits.

#include <boost/graph/two_bit_color_map.hpp>
#include <boost/variant.hpp>

int test1() {
    using namespace boost;
    boost::variant<int, char> v;
    int i = get<int>(v);
}

// make sure that it works even with incomplete types
struct S;

typedef boost::variant<boost::recursive_wrapper<S> > v_type;

void test2(v_type& v) {
    boost::get<S>(&v);
}
