[fw-general] private/procted in classes

[David Koblas]

I'm working on making an custom View class and have noticed that the 
private/protected is a little too strict (this possibly applies in other 
places). 

The specific case is that I went to override render -- after a bit of 
poking figured out I should override _run() instead.  But, in the 
process found that I had no access to the 'scriptPath' aka 
$this->_path['script'] variable to do my own implementation of the 
$this->_script() method.   Now that I'm back to my own render rountine 
have no access to the $this->_vars .  While I can go and write my own 
implementation on __set() it doesn't really make sense.

There probably is a more "framework friendly" approach to what I'm 
doing, but at the same time, extending the classes is a little bit of a 
bear.
