/** \def BOOST_VMD_TUPLE_REMOVE(tuple,index)

\brief removes an element from a tuple.

tuple = tuple from which an element is to be removed. <br/>
    index = The zero-based position in tuple of the element to be removed.

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