 * Admin notice class for wordpress plugin.
 * This class can not be initialized or extended.
 */

/**************************************************************************************************
 *  HOW TO USE.
 * After including this file, use the below example to start creating admin notice / review box
 *
 * Two arguments, id & message are required and can not be ommitied.
 * id must be unique for every message or it will override the previous message with same id.
 * 
 *               create a simple admin text message
 *   ctl_free_create_admin_notice( array('id'=>'bp-greeting-mesage','message'=>'Hey there!') );
 * 
 *              create a admin text error message
 * ctl_free_create_admin_notice( array('id'=>'bp-error-mesage','message'=>'this is an example of error!','type'=>'error') );
 * The argument 'type' can be: error, success, warning
 * 
 *              create a review box by passing minimum arguments
 * $slug = 'bp';
 * update_option($slug . '_activation_time,strtotime('now') ); // must create an activation time 
 * ctl_free_create_admin_notice( 
 *          array(
 *              'id'=>'bp_review_box',  // required and must be unique
 *              'slug'=>$slug,      // required in case of review box
 *              'review'=>true,     // required and set to be true for review box
 *              'review_url'=>'http://coolplugins.net', // required
 *              'plugin_name'=>'Boiler Plate Plugin',    // required
 *              'logo'=>'http://example.com/logo.png',   // optional: it will display logo
 *              'review_interval'=>5                    // optional: this will display review notice
 *                                                      //   after 5 days from the installation_time
 *                                                      // default is 3
 *          )
 * );
 * 
 * NOTE: Review box does not be displayed unless the $slug _activation_time is equals or
 * more than the 3 days from current time. This can also be changed by setting 'review_interval' arguments
