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).
