NOTES = """
This module provides facilities for serializable, validatable, and type-enforcing
domain objects.

This module has many of the same motivations as the python Marshmallow package.
<http://marshmallow.readthedocs.org/en/latest/why.html>

Also need to be explicit in explaining what Marshmallow doesn't do, and why this module is needed.
  - Provides type safety like an ORM. And like an ORM, all classes subclass Entity.
  - Provides BUILT IN serialization and deserialization.  Marhmallow requires a lot of code
    duplication.

This module gives us:
  - type safety
  - custom field validation
  - serialization and deserialization
  - rock solid foundational domain objects


Current deficiencies to schematics:
  - no get_mock_object method
  - no context-dependent serialization or MultilingualStringType
  - name = StringType(serialized_name='person_name')
  - name = StringType(serialize_when_none=False)
  - more flexible validation error messages
  - field validation can depend on other fields
  - 'roles' containing blacklists for .dump() and .json()


TODO:
  - alternate field names
  - add dump_if_null field option
  - add help/description parameter to Field


Optional Field Properties:
  - validation = None
  - default = None
  - required = True
  - in_dump = True
  - nullable = False

Behaviors:
  - Nullable is a "hard" setting, in that the value is either always or never allowed to be None.
  - What happens then if required=False and nullable=False?
      - The object can be init'd without a value (though not with a None value).
        getattr throws AttributeError
      - Any assignment must be not None.


  - Setting a value to None doesn't "unset" a value.  (That's what del is for.)  And you can't
    del a value if required=True, nullable=False, default=None.

  - If a field is not required, del does *not* "unmask" the default value.  Instead, del
    removes the value from the object entirely.  To get back the default value, need to recreate
    the object.  Entity.from_objects(old_object)


  - Disabling in_dump is a "hard" setting, in that with it disabled the field will never get
    dumped.  With it enabled, the field may or may not be dumped depending on its value and other
    settings.

  - Required is a "hard" setting, in that if True, a valid value or default must be provided. None
    is only a valid value or default if nullable is True.

  - In general, nullable means that None is a valid value.
    - getattr returns None instead of raising Attribute error
    - If in_dump, field is given with null value.
    - If default is not None, assigning None clears a previous assignment. Future getattrs return
      the default value.
    - What does nullable mean with default=None and required=True? Does instantiation raise
      an error if assignment not made on init? Can IntField(nullable=True) be init'd?

  - If required=False and nullable=False, field will only be in dump if field!=None.
    Also, getattr raises AttributeError.
  - If required=False and nullable=True, field will be in dump if field==None.

  - If in_dump is True, does default value get dumped:
    - if no assignment, default exists
    - if nullable, and assigned None
  - How does optional validation work with nullable and assigning None?
  - When does gettattr throw AttributeError, and when does it return None?

    Fields are doing something very similar to boxing and unboxing
