"""Assumption input and calculations for individual policies.
This Space is a child Space of :mod:`~simplelife.model.Projection`,
and it holds assumption parameters and rates used
by the :mod:`~simplelife.model.Projection` Space.

.. rubric:: Parameters
Since :mod:`~simplelife.model.Projection` is parameterized with
:attr:`PolicyID` and :attr:`ScenID`, this Space is also
parameterized as a child space of :mod:`~simplelife.model.Projection`.
For example, ``simplelife.Projection[1].Assumptions.ExpsMaintSA()``
represents the expense maintenance per sum assured for Policy 1.
Attributes:
PolicyID(:obj:`int`): Policy ID
ScenID(:obj:`int`, optional): Scenario ID, defaults to 1.
.. rubric:: References
Attributes:
AssumptionTables: `ExcelRange`_ object holding data read from the
Excel range *AssumptionTable* in *input.xlsx*.
MortalityTable: `ExcelRange`_ object holding mortality tables.
The data is read from *MortalityTables* range in *input.xlsx*.
