[boost] [serialization][test] Helping end-user testing serialisation

Hello everybody,

I think I have some idea that might improve the ease for the end user to 
test if he properly set-up his class for serialization.
Sorry if this idea has already been discussed (or even is already 
implemented), but I tried to search a little, without finding anything 
about this.

The main idea is that if an user has a serializable class, he will 
probably want to test wether he forgot to put some usefull member data 
in his |serialize function. Thus, he will have to write some test with 
always the same pattern. My suggestion is to put test_tools.hpp inside 
the serialization library, along with some template :|
||
|template<class T> void check_serialization(T const &t) // t should not 
be initialized to default values|
|{|
|    const char * testfile = boost::archive::tmpnam(NULL);|
|    BOOST_REQUIRE(NULL != testfile);|
|    {|
||        std::ofstream ofs(testFile);
|        boost::archive::text_oarchive oa(ofs);|
|        oa|| << t;|
|    }|
|    {
|||        T t1;
||        std::ifstream ifs(testFile, std::ios::binary);
|        boost::archive::text_iarchive ia(ifs);
|        ia >> t1      
|||    }|
|    BOOST_CHECK_EQUAL(t, t1);|
|    std::remove(testfile);|
|||}|
||||
Do you think it would make a worthy addition ?
