+ * Class: GeoExt.data.WMSCapabilitiesStore
+ * Small helper class to make creating stores for remote WMS layer data easier.
+ *     WMSCapabilitiesStore is pre-configured with a built-in
+ *     {Ext.data.HttpProxy} and {GeoExt.data.WMSCapabilitiesReader}.  The
+ *     HttpProxy is configured to allow caching (disableCaching: false) and uses
+ *     GET.  If you require some other proxy/reader combination then you'll have
+ *     to configure this with your own proxy or create a basic
+ *     GeoExt.data.LayerStore and configure as needed.

+/**
+ * Constructor: GeoExt.data.WMSCapabilitiesStore

+ *
+ * Parameters:

+ *
+ * Configuration options:
+ * format - {OpenLayers.Format} A parser for transforming the XHR response into
+ *     an array of objects representing attributes.  Defaults to an
+ *     {OpenLayers.Format.WMSCapabilities} parser.
+ * fields - {Array | Function} Either an Array of field definition objects as
+ *     passed to Ext.data.Record.create, or a Record constructor created using
+ *     Ext.data.Record.create.  Defaults to ["name", "type"].
