--> Implemented the following methods for dynamical semigroups:

1. multiply (*) : multiply two dynamical semigroups
2. power (^) : exponentiate a dynamical semigroup
3. nth_iterate : evaluate on a value n times with a dynamical semigroup
4. homogenize : convert affine dynamical semigroups to projective
dynamical semigroups
5. dehomogenize : convert projective dynamical semigroups to affine
dynamical semigroups

-->Implemented `orbit` and `specialization` methods for dynamical
semigroups.
<!-- Describe your changes here in detail -->
The orbit method works like the orbit method in dynamical systems, but
instead the point is evaluated on using a dynamical semigroup.

The specialization method returns a dynamical semigroup defined by the
specialization of the generators.
