    Allow streams to produce entire vectors as well as individual elements
    
    This is a signficant extension to the stream fusion mechanism. A Stream is now
    parametrised with a vector type and offers two iteration modes: individual
    elements and individual elements + vectors. This supports significantly more
    efficient implementations of block operations. For instance, (++) will now use
    memcpy where possible rather than iterating through the elements in a loop.
    
    Comments are sorely lacking at the moment.
