Directory and File browsing notes:


At this point, The basic file browsing is implemented in the mole

eg.

The bookmark/file browser expands, 
asks the various transport modules for trees, 
and displays the results.

This is true of the directory/file/image  browser

this primarly uses the add_


HOWEVER!

the method for updating and changing both the directory and file browser has not 
been defined.


eg.

If you modify an image, then the icon should refresh
If you add a file/directory etc. the tree should refresh.

refresh_node($bookmarkid, $URL, $nodedata)

// of if a directory is re-read

// directory contains 
  x
  y
  z
// read again only contains
  x
  y
 
// process currently 

bookmark browser
 - calls transport and asks for tree
 - loops through resulting array and 
   adds if it doesnt exist.
   
 - after adding, it should get the list of children,
   and see if any of them are not in the returned list
   and delete them.
