Transmogrified underlying data structure to a tree representation for flexibility reasons. Added a new Assigner module which calls the partitioner repeatedly to form a hierarchy.

Switch around examples at the end.

use a non-production channel.

1. tbbootconfig: ensure block is zeroed on first init, fix cut/paste error
2. rc.frisbee: cleanup interface to slicefix
3. slicefix: cleanup, make it work correctly, init tbboot block for cd boot

* On the shownode page include the channels that a wireless interface
  is currently set to, by looking at the interface_settings table. So,
  if you click on an allocated node in the wireless map, you can see
  what channels it is using.

  Still to be done; map between a channel number and a frequency.

* On the floormap page, create a small table at the top of the page,
  listing what frequencies are in use on each floor. This is rather
  primitive of course, especially the part where I assume we have just
  one building, but it will do for now.

This is not complete. We probably need some sense of scale on the
maps.

Needed for new PCs with SATA disks which start as "ad4".

project permission. By default you get a summary of all the free nodes
you can use in all your project memberships, which is not too
useful. It would be more useful to see what types you can use by
project, since that is how permission is granted and how experiments
are created. So, when you are a member of more than one project,
display a list of those projects along the top so you can see the list
on a per-project basis.

More generally, if you are an admin person:

	www.emulab.net/nodecontrol_list.php3?showtype=summary&bypid=tbres

will show out the summary information for a particular project. At
some point I need to make this a subroutine that we can call from
other pages to drop in a summary table.

system as well as the summary page.

For tbres/resweb (75 nodes):

	Old time: 42 seconds.
	New time: 19 seconds.

For testbed/BigLan (600 nodes):

	Old time: 120 seconds.
	New time: 40  seconds.

So, still needs some work, but for the average case its not so bad
anymore.

I also turn on compression to level 5 by default in our sshxmlrpc.py
library, thereby overriding the user's config file for that option.

You can look at the error code to figure out if it will ever be
possible to map this experiment onto the testbed.

partition by bootinfo, there actually is such a partition. This avoids
one instance Mike ran into in which the node got into a reboot loop
cause bootinfo said something that was not possible. So, run fdisk and
make sure the MBR has such a slice defined. If not, stay on the CD.

Add a section on using link_config and the XMLRPC interface to change
