- Added method ``get_model_instance_by_field_name`` to the ``GridH5ResultAdmin`` class. This makes it possible to do reverse lookups in situations where you have a field name but do not know which model it belongs to. N.B the field must be unique otherwise an ``IndexError`` will be raised.
- Added property ``dt_timestamps`` to the timeseries_mixin module.
- The version number is added to the ``__init__`` file dynamically using the ``pkg_resources`` API.
- Timestamps of all timeseries fields are shown for aggregation results.
- Timestamps in the aggregation results are filtered when retrieving subsets of timeseries.
- Introducing the ModelMeta class. Its main purpose at this moment is to compute all possible combinations of composite_fields and aggregation variables.
- Fixed return statement of method slice (in class Model) which now takes ``**new_class_kwargs``.
- Empty or missing datasets are now displayed as ``np.array(None)`` instead of raising an error.
