using the new assign, and captures Leigh's linkdelays work.

httpd.conf, so callinging it apache.conf and symlinking it is kinda
silly.

even when the delays table is not setup properly (cause its an
experiment swapped in under the old assign_wrapper).

De-"new!"-ification.
Added a "COOL" menu option, which puts up a gold star, without
lying. (e.g., for Join Netbed)

on end nodes). Add support for lans (only duplex links were really
supported). Finish up simplex vs duplex stuff wrt the delay_mapping
file. Some cleanup, but this program needs a total rewrite and I was
not in the mood.

Fixed problem in project approval page (unclosed "<p>" tag again)
and shrunk big thumbnail a bit in showexp.

Added PC Usage reporting to thumbnail view
Added "Sort-by" to thumbnail view
Changed "Show" so link is not presented to Show mode user is already on.
Changed "Show/View/Sort by" links to not change color after visited.

Added maximum node size in thumbnail;
So single node experiments won't visualize as a huge
green square, but rather a smaller one.

allow you to view interfaces that are not in an experiment.

Better headers on shownode page,
also added "Project" prefix to header on showproject and
"Experiment" prefix to header on showexp.

(Showing empty td's for pid="emulab-ops")

Added "brief thumbnails" view for Jay.

Added thumbnail (2x as large as the one which shows up in the list) to showexp page.
Added heading to vis(shownsfile), showexp and showproj pages, to more readily identify what you're looking at.
Added links from thumbnails to vis(shownsfile) page.
Added submenu hackiness to menu.php3 to allow embedding of things into left panel below submenu.
Removed "red letter" legend and PC  summary from bottom of thumbnail view.

fetch(1)

Fixed regexps to allow underscores.
('IDS_Eval/Bro_eval', for instance)

Stored in $TB/www/thumbs/,
with filenames generated by hashing random data with experiment name.
(Stored in vis_experiments table in db.)

vis prerender step setgid tbvis.

into the proper location.

(okay, a "*") in which case it means to not insert a specific node_id
into the event, but rather leave it to the subscribers to specify
what they need (in the case of the delay agent pid/eid/lan/lan-vnode.
The new assign_wrapper inserts these entries like this. Old stuff will
continue to work of course.

Now NS47-friendly, for the Luddites among us.

that allows the user to get a handle on that queue object so it
can be changed. Add a routine (lanlink) to the sim class that operates
much like link command (gets the hack class, which in turn is used to
get the queue object).

Note, there needs to be some work done in the event parser in sim.tcl
to deal with lan queues (assumed to be link queues). I'll take care of
that later.

Added "Created by:" to thumbnail view

2 columns instead of 3; also improved style a bit.
Still a ways to go.

Note the following: (from the API file)
  IMPORTANT: elvin uses timeouts internally. So, this function does
  NOT guarantee that when it returns, either an event has been
  recieved or your timeout has passed. This should not be much of
  a problem, but you have been warned!

The above is not really fixable, without hacking elvin. And it may
not be entirely fixable even then. In particular, the first call to
event_poll_blocking() will always return at once, since there are
leftover timers from connecting to elvind.

Added "thumbnail view" to Experiment List page.
Added thumbnail rendering to renderer.

Note that thumbnail view is not available when viewing the idle list.

Also, loading thumbnails for "all" as admin takes a while!
