+ * @class LLPanelInventoryListItemBase
+ *
+ * Base class for Inventory flat list item. Panel consists of inventory icon
+ * and inventory item name.
+ * This class is able to display widgets(buttons) on left(before icon) and right(after text-box) sides 
+ * of panel.
+ *
+ * How to use (see LLPanelClothingListItem for example):
+ * - implement init() to build panel from xml
+ * - create new xml file, fill it with widgets you want to dynamically show/hide/reshape on left/right sides
+ * - redefine postBuild()(call base implementation) and add needed widgets to needed sides,
+ *
