/**
* This class specifies the definition for a column inside a {@link Ext.grid.Panel}. It encompasses
* both the grid header configuration as well as displaying data within the grid itself. If the
* {@link #columns} configuration is specified, this column will become a column group and can
* contain other columns inside. In general, this class will not be created directly, rather
* an array of column configurations will be passed to the grid:
*
* @example
* Ext.create('Ext.data.Store', {
* storeId:'employeeStore',
* fields:['firstname', 'lastname', 'seniority', 'dep', 'hired'],
* data:[
* {firstname:"Michael", lastname:"Scott", seniority:7, dep:"Management", hired:"01/10/2004"},
* {firstname:"Dwight", lastname:"Schrute", seniority:2, dep:"Sales", hired:"04/01/2004"},
* {firstname:"Jim", lastname:"Halpert", seniority:3, dep:"Sales", hired:"02/22/2006"},
* {firstname:"Kevin", lastname:"Malone", seniority:4, dep:"Accounting", hired:"06/10/2007"},
* {firstname:"Angela", lastname:"Martin", seniority:5, dep:"Accounting", hired:"10/21/2008"}
* ]
* });
*
* Ext.create('Ext.grid.Panel', {
* title: 'Column Demo',
* store: Ext.data.StoreManager.lookup('employeeStore'),
* columns: [
* {text: 'First Name', dataIndex:'firstname'},
* {text: 'Last Name', dataIndex:'lastname'},
* {text: 'Hired Month', dataIndex:'hired', xtype:'datecolumn', format:'M'},
* {text: 'Department (Yrs)', xtype:'templatecolumn', tpl:'{dep} ({seniority})'}
* ],
* width: 400,
* forceFit: true,
* renderTo: Ext.getBody()
* });
*
* # Convenience Subclasses
*
* There are several column subclasses that provide default rendering for various data types
*
* - {@link Ext.grid.column.Action}: Renders icons that can respond to click events inline
* - {@link Ext.grid.column.Boolean}: Renders for boolean values
* - {@link Ext.grid.column.Date}: Renders for date values
* - {@link Ext.grid.column.Number}: Renders for numeric values
* - {@link Ext.grid.column.Template}: Renders a value using an {@link Ext.XTemplate} using the record data
*
* # Setting Sizes
*
* The columns are laid out by a {@link Ext.layout.container.HBox} layout, so a column can either
* be given an explicit width value or a flex configuration. If no width is specified the grid will
* automatically the size the column to 100px. For column groups, the size is calculated by measuring
* the width of the child columns, so a width option should not be specified in that case.
*
* # Header Options
*
* - {@link #text}: Sets the header text for the column
* - {@link #sortable}: Specifies whether the column can be sorted by clicking the header or using the column menu
* - {@link #hideable}: Specifies whether the column can be hidden using the column menu
* - {@link #menuDisabled}: Disables the column header menu
* - {@link #cfg-draggable}: Specifies whether the column header can be reordered by dragging
* - {@link #groupable}: Specifies whether the grid can be grouped by the column dataIndex. See also {@link Ext.grid.feature.Grouping}
*
* # Data Options
*
* - {@link #dataIndex}: The dataIndex is the field in the underlying {@link Ext.data.Store} to use as the value for the column.
* - {@link #renderer}: Allows the underlying store value to be transformed before being displayed in the grid
