Include ui.bootstrap for tabs
Add Map tab and simple Map from OpenLayers

Layout is tricky, OpenLayers.map likes to be in a div with a specific
width/height, and it seems to think the position is different.
Add markers with popup labels

Markers appear for societies after clicking 'Add Markers' button.  Need to refactor this to update when societies are updated.
Markers were appearing in wrong place until c17387145295de80e9ab3acca67af7bb081fd636
Use $scope.watchCollection to reload markers when societies change

Remove 'Add Markers' button
Allow find_societies to return empty set
