/**
 * This class used for generation content of columned pages with blocks.
 *
 * Example of using.
 * To create your own columned php page using this class you should follow these instructions:
 *
 * 1. Create in the root of your site file with chosen name. For example we will use example.php with following content:
 *
 * <?php
 *
 * require_once( 'inc/header.inc.php' );
 * require_once( BX_DIRECTORY_PATH_INC . 'design.inc.php' );
 * bx_import('BxDolPageView');
 *
 * class BxExamplePageView extends BxDolPageView {
 *     function BxExamplePageView() {
 *         parent::BxDolPageView('example'); // Attention! Here should be name which you will insert into sys_page_compose_pages in next step.
 *     }
 *
 *     // Here is functions that generate blocks on page. They are contain only contents of blocks.
 *     // You do not have to worry about it's title, design, etc. PageView class will make it itself.
 *
 *     // This function creates first block
 *     function getBlockCode_BlockOne() {
 *         return 'Hello world!';
 *     }
 *
 *     // This function creates another block with dynamic menu tabs
 *     function getBlockCode_BlockTwo() {
 *         return array(
 *              'I am Block Two. I have top menu!',
 *              array(
 *                  _t('_View') => array(
 *                      'href' => $_SERVER['PHP_SELF'] . '?view=true',
 *                      'dynamic' => true,
 *                      'active' => !$this->isEditable,
 *                  ),
 *                  _t('_Edit') => array(
 *                      'href' => $_SERVER['PHP_SELF'] . '?edit=true',
 *                      'dynamicPopup' => true,
 *                      'active' => $this->isEditable,
 *                  )
 *              )
 *        );
 *     }
 * }
 *
 * $_page['name_index']	= 0; // choose your own index of template or leave if in doubt
 * $_page['header'] = 'Example page';
 * $_ni = $_page['name_index'];
 *
 * $oEPV = new BxExamplePageView();
 * $_page_cont[$_ni]['page_main_code'] = $oEPV->getCode();
 *
 * PageCode();
 *
 * ?>
 *
 * 2. Insert into your sys_page_compose_pages table one line.
 *    Name - Unique identification name of the page. Used for association page with its blocks.
 *           We recommend use only latin symbols and digits. (In our example use "example")
 *    Title - Title of your page, it is shown in the Page Builder. ("Example page")
 *    Order - Just the order in list of pages in the Page Builder.
 *
 * 3. Insert into sys_page_compose lines for each block.
 *    ID - ID of the block. System field. Leave it by default (0). Will be passed to the function as first argument.
 *    Page - ID name of page which you inserted to sys_page_compose_pages ("example").
 *    PageWidth - System field. Leave it by default ("960px"). Customized later.
 *    Desc - Few words about this block. Description.
 *    Caption - Title of this block. ("Block One", "Block Two")
 *    Column - System field. Leave it by default (0). Customized later.
 *    Order - System field. Leave it by default (0). Customized later.
 *    Func - Name of function in your class (without prefix) which will be called to generate the block. ("BlockOne", "BlockTwo")
 *    Content - Optional argument. Rarely used. Passed as the second argument to the function.
 *    DesignBox - Number of Design Box (container). Leave it by default if in doubt (1).
 *    ColWidth - System field. Leave it by default (0). Customized later.
 *    Visible - System field. Leave it by default (0). Customized later.
 *    MinWidth - Minimum recommended width of the block.
 *
 * 4. Now go to the Page Builder, select your page in the list of pages and customize it (width, columns and blocks order).
      Then customize every block (caption, visibility, etc.).
 *
 * 5. Open http://yoursite.com/example.php in your browser and you will see your new customized columned page.
 *
