authentication & authorization
access control is determined by the metadata of a page.
the following metadata paths are relevent:
/peek/public
/poke/public
the values of these paths should be boolean 'flags'.
that is, a $dime where the aura is %f and the value is either .y or .n
if you set this attribute on a a page, it will be inherited by all sub-pages as well.
