test_modelTreeGui.py - test code for modelTreeGui.py (non-working)

@author: Will
@version: $Id$
@copyright: 2006-2008 Nanorex, Inc.  See LICENSE file for details.

update, bruce 081215:

This test code has not worked for a long time.
To run it at all (in its old location at the end of modelTreeGui.py),
it's necessary to use ExecSubDir (see comment below for details).

Then, the test_api call below, specifically, has bugs:

- it might reveal a bug in ExecSubDir.py, which fails to modify argv
  to remove itself as an argument and fix argv[0] to the expected value;

- the test_api code fails due to no args to __init__ in api class.

But commenting it out (and running with /ExecSubDir.py modelTree/modelTreeGui.py)
also fails:

  AssertionError: too early to call image_directory()

which is due to a recent new requirement in initializing NE1.

There are other similar recent requirements.
All could be solved, by adding some startup code to be called by all test code,
but since I doubt this test code works even once they are solved (since it wasn't
maintained across major finishings and rewrites of this module), it's not worth
the time for now.

So I will move it into an outtakes file, from which it could be
revived and fixed later if desired. I will not bother to port the
imports from that file. Note that that file may be split into several
smaller ones in the near future.
