Center map based on User's location?

I've been using Flask-GoogleMaps to display some companies that are partnering with us.

I would be great if we had a way to center the map based on user's location.
So then users could see easily all the markers around them.

For now, I'm using `request.access_route` to get user's IP/Location and then, set the `lat` and `lng` variables.

Wondering if it could be included in the next versions.

Start by reviewing how Flask-GoogleMaps currently receives lat and lng and renders the map, then compare that with the request.access_route approach described in the issue. Define the supported user-location source and verify that the map centers on that location while retaining nearby markers.
