heatmap

Description

Adds heatmap functionality to layers configured to support it (WMS-layers only at the moment). Configuration is done by adding the following information to a layers JSON:

{
    attributes : {
      geometryProperty : "the_geom",
      layerWorkspace : "ows",
      heatmap : ["properties to use", "as heatmap weighted property"]
    }
}

SelectedLayers bundle will show heatmap-enabled layers with an additional "Heatmap" tool in the layer frame to access the functionality. Note! Generated SLD expects Geoserver as the WMS-service.
