Header documentation of snpm_run_pp is not describing what the function does

[cmaumet]

Currently the header of snpm_run_pp is:

function out = snpm_run_pp(job)
% Example function that returns the sum of two numbers given in job.a and
% job.b in out. The output is referenced as out(1), this is defined in
% cfg_example_vout_add1.
%
% This code is part of a batch job configuration system for MATLAB. See 
%      help matlabbatch
% for a general overview.

which should be replaced by a description of what the function does.
