// However, by passing configs into the main container instead of objects, we can defer
// layout AND object instantiation until absolutely needed.  Since most of these panels
// won't be shown by default until requested, this will save us some processing
// time up front when initially rendering the page.
//
// Since all of these configs are being added into a layout container, they are
// automatically assumed to be panel configs, and so the xtype of 'panel' is
// implicit.  To define a config of some other type of component to be added into
// the layout, simply provide the appropriate xtype config explicitly.
