	  Grants are checked in the following way:
	  1) First all parents of this object are checked for grants for this
	     specific user. The 'nearest' grants are valid, and the path of
	     parent that set these grants will be the upper limit for the
	     checking of group grants.
	  2) Now all groups of which the user is a member are checked for
	     grants. Likewise, all parents are checked for group grants, upto
	     but not including the upperlimit as set in 1. All group grants
	     found are merged into one grants list.
	  3) If there are gropup grants, this means that there are group
	     grants set in a parent nearer to this object than the user grants
	     and therefore the groupgrants must be merged with the
	     usergrants.

	  this results in:
	  1	/		user: read edit		group: none
	  2	/dir/					group: read
	  3	/dir2/		user: none		group: read
	  4	/dir/dir3/				group2: edit
	  case 1: the user takes precedence over the group, grants are 'read edit'
	  case 2: groupgrants are merged with usergrants, as its grants are set
	          in a 'nearer' parent (itself). grants are 'read edit'.
	  case 3: user takes precedence again. grants are 'none'.
	  case 4: All group grants are merged with the usergrants.
	          Therefore the grants are 'none read edit'.

  "safe" functions.

  The following functions are safe versions of existing functions
  above.
  - They don't change anything in the database.
    This means that to save/delete something, a user will need to call
    "system.save.data.phtml" or "system.delete.phtml" which check grants.
  - All functions except _get and _exists don't take a path as
    argument, they use the current objects path instead.

  These are meant to be used by 'pinp' versions of templates,
  meaning user defined templates. 'pinp' rewrites call to functions
  to the form '$this->_function'.

  All pinp files automatically first call CheckLogin('read').
