add register page (using bootstrap)
add namespace
modify the home path to be the bamboo path
use the redbean.php in the model
notice:
    the redbean.php use the default
        class_exists($classname)
    and all need to be modified as :
        class_exists($classname,false)
    or it will throw a LogicException
    because the class_exists will try to autoload the $classname
