Wrote 2 arg unit tests for the noe.spectrum_type() user function.

Modified the noe user function class docstring.

Modified the noe.spectrum_type() docstring to emphasis that it is for the steady-state NOE.

Moved the 'spin_id = generate_spin_id(res_num=res_num, spin_name=X_name)' instance into the
different intensity_*() functions.

This is as suggested in a thread started by Edward at:

(Message-id: <7f080ed10812040706v3fadaa2eh2f475aa4ab611da7@...>)

Created a new data pipe for relaxation dispersion analyses.

Fix for the spectrum.read_intensities() user function.

The sep arg was being ignored.

Fix for the value.read() user function.

The directory and 'sep' args were being ignored.

Changed a RelaxError so it is more appropriated.

This is as proposed in the commit for r8137.

Modified the autodetection code for the generic format.

This now recognizes the most generic format as in
'test_suite/shared_data/peak_lists/generic_intensity2.txt'.

Modified the check for the spectrum_id being a string, a list is now accepted as well.

This is needed to implement the list of spectrum_id as in 'test_suite/system_tests/peak_lists.py'
(test_read_peak_list_generic2() function).

Should the RelaxStrError be changed to something like a RelaxStrListError ?
