/**
* This feature is used to place a summary row at the bottom of the grid. If using a grouping,
* @author mperez
* see {@link Ext.grid.feature.GroupingSummary}. There are 2 aspects to calculating the summaries,
* mostly a copy of the feature.summary.
* calculation and rendering.
*
* ## Calculation
* The summary value needs to be calculated for each column in the grid. This is controlled
* by the summaryType option specified on the column. There are several built in summary types,
* which can be specified as a string on the column configuration. These call underlying methods
* on the store:
*
* - {@link Ext.data.Store#count count}
* - {@link Ext.data.Store#sum sum}
* - {@link Ext.data.Store#min min}
* - {@link Ext.data.Store#max max}
* - {@link Ext.data.Store#average average}
*
* Alternatively, the summaryType can be a function definition. If this is the case,
* the function is called with an array of records to calculate the summary value.
*
* ## Rendering
* Similar to a column, the summary also supports a summaryRenderer function. This
* summaryRenderer is called before displaying a value. The function is optional, if
* not specified the default calculated value is shown. The summaryRenderer is called with:
*
* - value {Object} - The calculated value.
* - summaryData {Object} - Contains all raw summary values for the row.
* - field {String} - The name of the field we are calculating
*
* ## Example Usage
*
* @example
* Ext.define('TestResult', {
* extend: 'Ext.data.Model',
* fields: ['student', {
* name: 'mark',
* type: 'int'
* }]
* });
*
* Ext.create('Ext.grid.Panel', {
* width: 400,
* height: 200,
* title: 'Summary Test',
* style: 'padding: 20px',
* renderTo: document.body,
* features: [{
* ftype: 'summary'
* }],
* store: {
* model: 'TestResult',
* data: [{
* student: 'Student 1',
* mark: 84
* },{
* student: 'Student 2',
* mark: 72
* },{
* student: 'Student 3',
* mark: 96
* },{
* student: 'Student 4',
* mark: 68
* }]
* },
* columns: [{
* dataIndex: 'student',
* text: 'Name',
* summaryType: 'count',
* summaryRenderer: function(value, summaryData, dataIndex) {
* return Ext.String.format('{0} student{1}', value, value !== 1 ? 's' : '');
* }
* }, {
* dataIndex: 'mark',
* text: 'Mark',
* summaryType: 'average'
* }]
* });
