Added missing arguments.

Added a missing argument.

Continued to add the support for the generic peak intensity file and ordered things alphabetically.

Created a class named Peak_lists including the classes Generic, NMRView, Sparky and Xeasy.

This solves a name clash pointed out in a post at:

(Message ID: 48F8E785.8090106@...)

and was proposed by Edward in a post at:

(Message ID: 7f080ed10810171437s2103ba32pdf9f10d1ffe0230e@...)

Fixed the contents of the class docstring.

This was incorrectly mentioning relaxation curve-fitting and was identified by Seb.

Ordered functions alphabetically.

Added more to the system test for the generic peak intensities file.

Added a generic peak intensities file including the delay times.

This is in response to r7799
(http://svn.gna.org/viewcvs/relax?rev=7799&view=rev)

Added prototypes for the generic peak intensities file.

Only two files will be needed, instead of one file per delay. The first file (generic_delay.txt)
will contain the different delays. The second file (generic_intensity.txt) will contain the peak
intensities.

There may also be a way of including all this information in one single file... maybe by putting
the delays in the header ? This would be even simpler for the user who would only need to input 1
single file.

Started to write a system test for the support of the generic peak intensities file.
