Introduced the generate_spin_id_data_array() function in the generic intensity file code.

The code now support a 'fake' generic format (with defined columns). Much more work is needed to
make this code more versatile to support 'any' format.

This follows a post by Edward at:

Wrote 7 arg unit tests for the as of yet non-existent noe.read() user function.

Renamed the 2 unit tests committed at r8146.

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:
