New description:

 This is the implementation of topological manifolds over a topological
 field ''K'' resulting from the [http://sagemanifolds.obspm.fr/
 SageManifolds project]. See the meta-ticket #18528 for an overview.
 By ''topological manifold over a topological field K'' it is meant a
 second countable Hausdorff space ''M'' such that every point in ''M'' has
 a neighborhood homeomorphic to ''K^n^'', with the same non-negative
 integer ''n'' for all points.

 This tickets implements the following Python classes:

 - `ManifoldSubset`: generic subset of a topological manifold (the open
 subsets being implemented by the subsclass `TopologicalManifold`)
   - `TopologicalManifold`: topological manifold over a topological field
 ''K''
 - `ManifoldPoint`: point in a topological manifold
 - `Chart`: chart of a topological manifold
   - `RealChart`: chart of a topological manifold over the real field
 - `CoordChange`: transition map between two charts of a topological
 manifold

 as well as the singleton classes`TopologicalStructure` and
 `RealTopologicalStructure`.

 `TopologicalManifold` is intended to serve as a base class for specific
 manifolds, like smooth manifolds (''K''='''R''') and complex manifolds
 (''K''='''C'''). The follow-up ticket, implementing continuous functions
 to the base field, is #18640.

 '''Documentation''':
 The reference manual is produced by
 `sage -docbuild reference/manifolds html`
 It can also be accessed online at
 http://sagemanifolds.obspm.fr/doc/18529/reference/manifolds/
 More documentation (e.g. example worksheets) can be found
 [http://sagemanifolds.obspm.fr/documentation.html here].
