"""Assumption input and calculations for individual policies.
This Space holds the outer or inner projection assumptions
for each individual model point.
.. figure:: /images/projects/nestedlife/model/Assumptions/diagram1.png
.. rubric:: Parameters
This Space is a child Space of :mod:`~nestedlife.model.BaseProj`.
Since :mod:`~nestedlife.model.OuterProj` and its
child Space :mod:`~nestedlife.model.OuterProj.InnerProj` both inherit
:mod:`~nestedlife.model.BaseProj`,
Both :mod:`~nestedlife.model.OuterProj` and
:mod:`~nestedlife.model.OuterProj.InnerProj` inherit this Space
as their child Spaces.
Since :mod:`~nestedlife.model.OuterProj` is parameterized with
:attr:`PolicyID` and :attr:`ScenID`, the ``Assumptions`` Space
derived from this Space is also
parameterized as a child space of :mod:`~nestedlife.model.OuterProj`.
For example, ``nestedlife.Projection[1].Assumptions.ExpsMaintSA()``
represents the assumption of maintenance expense per sum assured for Policy 1
for the outer projection.
:mod:`~nestedlife.model.OuterProj.InnerProj` is parameterized with
``t0``, the time at which the inner projection starts,
so its ``Assumptions`` child Space derived this Space is
also parameterized
as a child space of :mod:`~nestedlife.model.OuterProj.InnerProj`.
Attributes:
PolicyID(:obj:`int`): Policy ID
ScenID(:obj:`int`, optional): Scenario ID, defaults to 1.
