New description:
This ticket implements morphisms of topological manifolds, i.e. continuous
maps between topological manifolds. This is a follow-up of #18640 within
the [http://sagemanifolds.obspm.fr/ SageManifolds project]. See the
metaticket #18528 for an overview.
Two new Python classes are introduced in this ticket:
- the parent class `TopManifoldHomset` for sets Hom(M,N) of morphisms
between two
topological manifolds M and N over the same topological field K
- the element class `ContinuousMap` for elements of Hom(M,N), i.e.
continuous maps M --> N
Moreover, this ticket introduces plotting capabilities for charts (method
`RealChart.plot()`) and for points (method `TopManifoldPoint.plot()`),
which require continuous maps and thus could not have been introduced in
#18529.
