/** \def BOOST_VMD_SEQ_REMOVE(seq,index)

    \brief removes an element from a seq.

    seq = seq from which an element is to be removed.
    index = The zero-based position in seq of the element to be removed.

    If index is greater or equal to the seq size the result is undefined.
    If the seq is a single element and the index is 0 the result is an empty seq.
    Otherwise the result is a seq after removing the index element.
