.. This is an example of calibration source code::

..    import os
..    import snls.calib as calib
..    import snls.io as io

..    assoc = calib.Associations()
..    for im in im_names:
..      exp = io.open(im)
..      assoc.append_shoot( exp )

..    assoc.associate()

.. And this is another example::

..    model = calib.GridModel(4,9)
..    grid_fitter = calib.GridFitter( model, assoc )
..    try:
..      grid_fitter.fit()
..    except calib.GridFitException, e:
..      print e.msg()
..    except:
..      ...
