    shrinkable map, so I can reference it for Urs’ question on Hurewicz fibrations.

    Urs prettied up shrinkable map, and added it as an example to Dold fibration (with a little correction from me: we don’t need a numerable cover to be good for its geometric realisation to have shrinkable projection).

    Added comment that the implication shrinkable \Rightarrow Dold fibration is a theorem about locally homotopy trivial maps, and that a shrinkable map is globally homotopy trivial with trivial fibre.
