To bundle all model classes and the functionality from ``gammapy.utils.fitting``
into a single namespace, a new ``gammapy.modeling`` subpackage was introduced.
All spectral, spatial, temporal and combined models were moved to the
``gammapy.modeling`` subpackage and renamed following a consistent naming

+scheme. This provides a much clearer structure of the model types and hierarchy

+
+A new ``ConstantTemporalModel`` was introduced and the ``GaussianSpatialModel``
now supports elongation parameters. A bug that lead to an incorrect flux
normalisation of the ``PointSpatialModel`` at high latitudes was fixed.
The default coordinate frame for all spatial models was changed to ``icrs``.
