/** \def BOOST_VMD_ASSERT_IS_SEQ(sequence)

    \brief Asserts that the sequence is a Boost PP seq.

    The macro checks that the sequence is a Boost PP seq.
    If it is not a Boost PP seq, it forces a compiler error.
    
    The macro normally checks for a Boost PP seq only in 
    debug mode. However an end-user can force the macro 
    to check or not check by defining the macro 
    BOOST_VMD_ASSERT_DATA to 1 or 0 respectively.

    sequence = a possible Boost PP seq.

    returns  = Normally the macro returns nothing. 
    
               If the sequence is a Boost PP seq, nothing is 
               output.
              
               For VC++, because there is no sure way of forcing  
               a compiler error from within a macro without producing
               output, if the sequence is not a Boost PP seq the 
               macro forces a compiler error by outputting invalid C++.
              
               For all other compilers a compiler error is forced 
               without producing output if the sequence is not a 
               Boost PP seq.
