This ticket adds an example of a magma.

sage: M = Magmas().example(); M
An example of a magma: the free magma generated by ('a', 'b', 'c', 'd')
sage: a, b, c, d = M.magma_generators()
sage: a * (b * c) * (d * a * b)

This is in part motivated by this ask-sagemath question and by the seeming lack of magmas in Sage.
