IsTopologicalGroup

A topological group is a group in which the multiplication and inversion operations are continuous. When you declare an instance that does not already have a UniformSpace instance, you should also provide an instance of UniformSpace and IsUniformGroup using IsTopologicalGroup.rightUniformSpace and isUniformGroup_of_commGroup.
