Update usage to use require("collections/map").CollectionsMap

[gimite]

Looks require("collections/map") returns JS's built-in Map type when available, which is not 100% compatible with Map in collections.js e.g., equals, hash parameters are not available.

So how about updating the usage to use require("collections/map").CollectionsMap, to match the rest of the documentation?

If that still true that interesting i would may be instead make sure require("collections/map") instead return collectionJS map Shim instead of original one personally.
