Test comparisons done by globbing all unittests and diff'ing the output:

	glob-test()
	{
		{
		for script in *.py; do
			echo -e "[ $script ]"
			./$script
		done
		} > /tmp/calibration_estimation-test-$(git rev-parse --short HEAD).txt 2>&1
	}
	roscd calibration_estimation/test
	git checkout hydro-devel
	glob-test
	git checkout feature/urdf-parser-py
	glob-test

	git diff -u /tmp/calibration_estimation-test-{cdebb47,7e4c234}.txt

This produces no difference.


NOTE: Several tests do not pass. The following tests fail:

	$ for script in *.py; do ./$script > /dev/null 2> /dev/null || echo $script; done
	camera_chain_sensor_unittest.py
	chain_sensor_unittest.py
	checkerboard_unittest.py
	opt_runner_unittest.py
	urdf_unittest.py


camera_chain_sensor_unittest.py
	Depends on old robot_params, but that was moved / refactored into urdf_params in 8f6903fd (2011-12-05)
urdf_unittest.py:
	Depends on /tmp/pr2_calibration/cal_measurements.bag
