Small bug in op_averaging.m, when input data only has 1 average (out not returned)? #104

Hi,

I obtained an error message, when applying the routine op_averaging to a water signal with only 1 average.
"Output argument "out" (and maybe others) not assigned during call to "op_averaging".

The corresponding code in op_averaging.m reads:

function out=op_averaging(in);

if in.flags.averaged || in.averages<2
%DO NOTHING
disp('WARNING: No averages found. Returning input without modification!');
return;
end

if in.dims.averages==0
%DO NOTHING
disp('WARNING: No averages found. Returning input without modification!');
out=in;
return;
else
...

I guess in the first if-statement that checks if # of averages is below 2, the line
out=in;
is missing, which in my case leads to the error message mentioned above.

Adding the line
out=in;
fixed this error.
