    Created stub for Spin group. Made a mess of explaining why it is so named.

    I have added a list of exceptional isomorphisms in low dimensions to Spin group

    I am really after what happens for Spin(6,2)Spin(6,2). But that seems to be a longer story…

    I have finally added the actual definition via Clifford algebra at spin group. Also at spin representation.
