Source code for solvency2.model.Assumptions

"""Assumption input and calculations for individual policies.

This Space holds projection assumptions
for each individual model point.

This Space is parameterized with :attr:`PolicyID`,
and each ItemSpace of this Space is referenced in
the Projection Spaces under the ItemSpace of SCR_life
that has the same PolicyID as the ItemSpace of this Space.

For example ``Assumptions[1]`` is referenced in
``SCR_life(1).Projection(Risk)`` as ``asmp``, where Risk is 'base', 'mort',
'longev',... etc.
