Converted all the extern.numdifftools modules using the dos2unix program.

Python 3 fixes using 2to3 for the extern.numdifftools package.

The command used was:
2to3 -j 4 -w -f except -f import -f imports -f long -f numliterals -f xrange .

Python 3 fixes using 2to3 for the extern.numdifftools package (mainly spacing fixes).

The command used was:
2to3 -j 4 -w -f buffer -f idioms -f set_literal -f ws_comma -x except -x import -x imports -x long -x numliterals -x xrange .

Fixes for the Relax_disp.test_hansen_cpmg_data_missing_auto_analysis system test for certain systems.

The optimisation precision has been increased, and the value checking precision has been decreased.
This change is to allow the test to pass on Python 2.5 and 3.1 on a 32-bit GNU/Linux system. This
may be related to 32-bit numpy 1.6.2 verses later numpy versions causing precision differences.

Python 3 fixes - eliminated all usage of the dictionary iteritems() calls as this no longer exists.

Python 3 fixes throughout relax, as identified by the 2to3 script.

The command used was:
2to3 -j 4 -w -f except -f import -f imports -f long -f numliterals -f xrange .

Python 3 fixes for the relax codebase.

These changes were made using the command:
2to3 -j 4 -w -f buffer -f idioms -f set_literal -f ws_comma -x except -x import -x imports -x long -x numliterals -x xrange .

Fix for the Relax_disp.test_cpmg_synthetic_dx_map_points system test for certain systems.

This change is to allow the test to pass on Python 2.5 and 3.1 on a 32-bit GNU/Linux system. This
may be related to 32-bit numpy 1.6.2 verses later numpy versions causing precision differences.

Loosened the checks in the Relax_disp.test_baldwin_synthetic_full system test.

This is to allow the test to pass on Python 2.5 and 3.1 on a 32-bit GNU/Linux system.

Removed debugging code from the N_state_model.test_CaM_IQ_tensor_fit system test.

This was an accidentally introduced state.save user function used to catch the system test state.
It would results in the 'x.bz2' file being dumped in the current directory. It was introduced in
r26359 (http://article.gmane.org/gmane.science.nmr.relax.scm/24110).
