/* gmap plugin.
*
* $.gmap()
* $.gmap({ ...options... })
* $.gmap('addMarkers', data)
*
* The jQuery object being mapified must have an attribute: data-initial-view="lat,lng,zoom"
*
* Configuration options:
*
* loadingMessage: a string for the loading overlay. Default: "Loading..."
* autoAddMarkers: boolean. If true, a marker is automatically added for each item with the
* attribute data-marker-info="lat,lng". If the element or any descendant has the class
* "ui-gmap-marker-content", then an infobox containing that content will be shown when
* the marker is clicked (this content is cloned). The HTML contents of a subelement with
* class "ui-gmap-marker-title" will be used for the mouseover tooltip.
* infoWindowConfig: Object containing a list of properties for the info window (if applicable).
*
* Markup requirements:
*
* 1. The class "ui-gmap" will be added to each element to which the plugin is applied.
