Example
*******
The creation of the object hypo_1 is done as follows:
::

    hypo_1 = homard.CreateHypothesis("HypoField")
    hypo_1.SetAdapRefinUnRef(1, 1, 0)
    hypo_1.SetField("INDICATEUR")
    hypo_1.AddComp("INDX")
    hypo_1.AddComp("INDZ")
    hypo_1.SetRefinThr(1, 80.)
    hypo_1.AddFieldInterp("DEPL")
    hypo_1.AddFieldInterpType("MASS", 1)

In python mode, that is not true: the iterations stay as they are.
