Polyline when :provider => "openlayers"

[atejeda]

As was suggested in https://github.com/apneadiving/Google-Maps-for-Rails/issues/215

I've added polyline for openlayer. The json structure to use is the same used for google maps (as provider), same thing for the styling.

I've used the same example of "Display Everything.."

<%= 
gmaps({ 
"map_options" => { :provider => "openlayers", "zoom" => 2, "auto_adjust" => true }, 
"markers"     => { "data" => '[{ "description": "", "title": "", "lng": "5.9311119", "lat": "43.1251606", "picture": "", "width": "", "height": "" } ,{   "description": "", "title": "", "lng": "2.3509871", "lat": "48.8566667", "picture": "", "width": "", "height": "" } ]',
                                     },
"polylines"   => { "data" => ' [ [
                     {"lng": -122.214897, "lat": 37.772323},
                     {"lng": -157.821856, "lat": 21.291982},
                     {"lng": 178.431, "lat": -18.142599},
                     {"lng": 153.027892, "lat": -27.46758}
                     ],
                     [
                     {"lng": -120.214897, "lat": 30.772323, "strokeColor": "#000", "strokeWeight" : 2 },
                     {"lng": -10.821856, "lat": 50.291982}
                     ] ]' }
}) %>
