/*
 * The Flow
 *
 * view.html.php
 * -> get all columns set by options
 *
 * HEADER (default.php) RENDER COLUMN HEADER
 *
 * -> renderHeader() -> all columns iterate in foreach
 * -> header() -> column will be transformed to function
 * -> e.g. skuHeader() -> all column data will be defined here, possible change for each view
 * -> renderHeaderColumn() -> rendering of column HTML header
 *
 * BODY (default.php) RENDER COLUMN BODY
 *
 * -> foreach -> all columns iterate in default.php
 * -> item -> column will be transformed to function
 * -> e.g. sku -> commonColumn -> sku function calls commonColumn (e.g. title renders HTML immediately) - possible change for each view
 * -> commonColumn() -> rendering of column HTML body
 *
 * SORTFIELDS (view.html.php) RENDER SORT FIELDS
 *
 * -> renderSortFields() -> all columns iterate in foreach
 * -> header() -> column will be transformed to function
 * -> e.g. skuHeader -> all column data will be defined here, possible change for each view - RETURNS DATA!!!, does not render column header
