 * The DataTable_Simple is used to provide an easy way to create simple DataGrid.
 * A DataTable_Simple actually is a DataTable with 2 columns: 'label' and 'value'.
 * 
 * It is usually best to return a DataTable_Simple instead of 
 * a PHP array (or other custom data structure) in API methods:
 * - the generic filters can be applied automatically (offset, limit, pattern search, sort, etc.)
 * - the renderer can be applied (XML, PHP, HTML, etc.)
 * So you don't have to write specific renderer for your data, it is already available in all the formats supported natively by Piwik.
