simplify generic serial result layer view GeoJSONResultLayerData #38

instead of passing model_name and custom_property via init it's is now taken from subclass attribute

-    Notes
-    -----
     Different from static serial layer views (examples see above) which use a
     specific model each, this view uses the dummy model
     :class:`stemp_abw.models.ResultLayerModel` on initialization. The property
     "model" which is required by djgeojson is set dynamically using class
     method :meth:`stemp_abw.models.ResultLayerModel.name_init`.
+
+    Attributes
+    ----------
+    model_name : :obj:`str`
+        Name string of model (used as property "name" in dummy model
+        :class:`stemp_abw.models.ResultLayerModel), see model for detailed
+        description.
+    custom_property : :obj:`str`
+        Property (column) to be added to model, must be a column in
+        layer results DataFrame results_df.
+    properties : :obj:`list` of :obj:`str`
+        Properties for each feature to be contained in the GeoJSON.
