 *  
 *      Small helper class to make creating stores for remote WMS layer description
 *      easier.  The store is pre-configured with a built-in
 *      ``Ext.data.HttpProxy`` and :class:`GeoExt.data.WMSDescribeLayerReader`.
 *      The proxy is configured to allow caching and issues requests via GET.
 *      If you require some other proxy/reader combination then you'll have to
 *      configure this with your own proxy or create a basic
 *      store and configure as needed.
