Description
Modified from the Lasso siteAdmin tags, this tag allows you to define a variable, assign it to a session, validate when setting from an action parameter, force a value, and set a default value.
Sample Usage
var_define('route', -default=string, -override=action_param('route'), -validate=array('login', 'settings', 'session', 'interest', 'search'));
var_define('legal', -override=action_param('legal'), -session='mysession');
