Handle namespace provides

Browse Source 
It looks like the convention in the Closure Library is to export either namespaces (starting with lowercase), constructors (starting with uppercase), or enums (all uppercase, one instance).  I don't see any places where the Closure Library exports a function that is not a constructor.

Following the same convention, when we export `ol.foo`, it means we are making available function properties of the `ol.foo` object that start with a lowercase letter.
