composite_algebra

[mariomulansky]

As discussed in the emails we should add a composite_algebra that works on tuples (or fusion::vectors) of different state types. A possible definition of such an algebra could look as follows:

typedef tuple< vector<complex> , double > state_type;
typedef composite_algebra< tuple< range_algebra , vector_space_algebra > > algebra;
