/**
 * @class mapfish.widgets.MapComponent
 * @extends Ext.Container
 * A map container in order to be able to insert a map into a complex layout
 * Its main interest is to update the map size when the container is resized
 * Simple example usage:
 * <pre><code>
 * var mapcomponent = new mapfish.widgets.MapComponent({map: map});
 * </code></pre>
 * Note that the callback method must return a valid <OpenLayers.Map> object
 * @constructor
 * Create a new MapComponent
 * @param {Object} map the OpenLayers map object
 * @param {Object} config The config object
