Use RouteBoxer without google maps library

[NoamDev]

I'd like to use RouteBoxer outside the context of google maps api.
But it uses classes like google.maps.LatLng, google.maps.Polygon, google.maps.LatLngBounds etc. which are missing when I try to use it independently.
Is there a lightweight package which contains all those structures?
