MetacatUI

The GoogleMaps was freezing up (and crashing the browser in some instances) when a cluster was clicked on at max zoom level. I found that the markerclusterer plugin has trouble syncing the Google Map max zoom property and the MarkerClusterer max zoom property. When I set the clusterer max zoom to 15 and the map max zoom to null, everything seems to work okay. Any other combination triggers a map event (either fitBounds or zoom), triggering many metacat searches and freezing up the map.

This issue also caused me to notice that at max zoom, if you click on a cluster, the cluster disappears. So I patched the MarkerClusterer plugin to fix that according to https://code.google.com/p/google-maps-utility-library-v3/issues/detail?can=2&start=0&num=100&q=&colspec=ID%20Type%20Status%20Priority%20Fixed%20Owner%20Summary%20Stars&groupby=&sort=&id=210.
