/**
* @class
* The TimeMap object holds references to timeline, map, and datasets.
*
* @constructor
* This will create the visible map, but not the timeline, which must be initialized separately.
*
* @param {DOM Element} tElement The timeline element.
* @param {DOM Element} mElement The map element.
* @param {Object} [options] A container for optional arguments
* @param {TimeMapTheme|String} [options.theme=red] Color theme for the timemap
* @param {Boolean} [options.syncBands=true] Whether to synchronize all bands in timeline
* @param {LatLonPoint} [options.mapCenter=0,0] Point for map center
* @param {Number} [options.mapZoom=0] Initial map zoom level
* @param {String} [options.mapType=physical] The maptype for the map (see {@link TimeMap.mapTypes} for options)
* @param {Function|String} [options.mapFilter={@link TimeMap.filters.hidePastFuture}]
* How to hide/show map items depending on timeline state;
* options: keys in {@link TimeMap.filters} or function. Set to
* null or false for no filter.
* @param {Boolean} [options.showMapTypeCtrl=true] Whether to display the map type control
* @param {Boolean} [options.showMapCtrl=true] Whether to show map navigation control
* @param {Boolean} [options.centerOnItems=true] Whether to center and zoom the map based on loaded item
* @param {String} [options.eventIconPath] Path for directory holding event icons; if set at the TimeMap
* level, will override dataset and item defaults
* @param {Boolean} [options.checkResize=true] Whether to update the timemap display when the window is
* resized. Necessary for fluid layouts, but might be better set to
* false for absolutely-sized timemaps to avoid extra processing
* @param {Boolean} [options.multipleInfoWindows=false] Whether to allow multiple simultaneous info windows for
* map providers that allow this (Google v3, OpenLayers)
