Description

The most common examples in (differential) geometry are the Euclidean space, the sphere and the hyperbolic space, namely the manifolds with constant sectional curvature 0, 1 and -1. I suggest, we add the sphere and hyperbolic space in a similar manner as it has already been done for EuclideanSpace.

This is also a good opportunity to expand the tutorials a little bit. Furthermore, most of our docstring examples are based on the 2-sphere. Hence we can perhaps shorten or simplify some parts of the documentation.
