Log Message:
First working version of a new optimization package that uses a slightly
modified version of m1qn3, v3.3 
(https://who.rocq.inria.fr/Jean-Charles.Gilbert/modulopt/optimization-routines/m1qn3/m1qn3.html)
to work as an offline optimizer. The advantage of m1qn3_offline is, that 
it is run in reverse communication control mode, so that it gives back
control to the call routine (here a script) to provide a new estimate of the
cost function and the gradient based on the control vector. This way we can
do complete line searches that are meaningful.
