Toolbar with go to location and zoom out

[soft-boy]

User story:

from an information architecture point of view, the "go to location" and "zoom out" functionalities in the nav don't fit in with the others. With consideration of the future arrival of choropleth and heat map functionalities, there should be a tool bar on the map that contains these functionalities.

Specific requirements/functionality:

The "go to location" and "zoom out" button should be gone from the nav. There should a new component floating right and center with "go to location" and "zoom out." Should easily allow extending with choropleth and heat map
