/**
* This class encapsulates the user interface for a tabular data set.
* It acts as a centralized manager for controlling the various interface
* elements of the view. This includes handling events, such as row and cell
* level based DOM events. It also reacts to events from the underlying {@link Ext.selection.Model}
* to provide visual feedback to the user.
*
* This class does not provide ways to manipulate the underlying data of the configured
* {@link Ext.data.Store}.
*
* This is the base class for both {@link Ext.grid.View} and {@link Ext.tree.View} and is not
* to be used directly.
