Added
* Added to `Model.to_dict` and `Model.serialize` a parameter, `serial_list`,
`serial_list` enables displacing the class `SERIAL_LIST` attribute for
on an ad hoc basis to the fields that are included in serialization.
* Added a class attribute, `RELATION_SERIAL_LISTS`, to better control the
output of relations. The new variable is a dict where the key is a
relationship field and the value is the explicit list of fields that
would be included in serialization. The advantage is that a standard
list of fields for the secondary relationship variable does not have to
define the output for the primary serialization. Just as a `serial_list`
parameter has been added to Model.to_dict and Model.serialize, a
`relation_serial_lists` has been added as well for convenience.
Changed
* Trivially changed utils._xlate_from_js to utils._xlate_from_camel_case
for clarity.
* Changed `Model._get_serial_stop_list` from a class method. It is only
useful with an instance.
Fixed
* Fixed `Model._class()` function. When used as part of a Python package, it
identified the class as DeclarativeMeta rather than the correct class
name. Also, it now works for Postgres materialized views.
