/**
* A simple extension for create where strings with checking.
*
* With this extension, you can create sql strings for use on where parameter of select method from Webmodel.
*
* Example ['AND']->array( 'field' => array('!=', 25), 'field2' => array('=', 'value_field'), 'field3' => array('LIKE', 'value_field'), 'field4' => array('IN', array('1','2','3'), 'limit_sql' => array('LIMIT', array(1, 10), 'order_by' => array('order_fieldY', 'ASC'
))
*
* You can join differents sql sentences
*
* @warning Experimental, don't use in production
