This PR defines the set of routes in Canada which are equivalent in national importance to the US Interstate Highway System, and are therefore appropriate to render at zoom 4. This creates a sane, connected highway network at this zoom level across the USA and Canada. This adds two additional network types for Canadian highways, ca-provincial for provincial-level roads, and ca-provincial-arterial for "highest importance" roads that are not part of the Trans-Canada highway but should be regarded as equivalent for low-zoom rendering purposes. Additionally, this extracts out the country-specific network checks to a separate function in order to define "equivalent top-level networks" by country, providing a place to add additional national definitions as they're added by contributors.

This is the layer for labelling the highways. Only highways that are named `name=*` and are long enough
|
|
to place text upon appear. The OSM roads are stitched together if they contain the same name
|
|
to have better label placement than having many small linestrings.
|
|
For motorways you should use the `ref` field to label them while for other roads you should use `name`.

|
name_de: German name `name:de` if available, otherwise `name` or `name:en`.

ref: The OSM [`ref`](http://wiki.openstreetmap.org/wiki/Key:ref) tag of the motorway or its network.
