'''
Constructor for a new solver for problems with risky income, a different
interest rate on borrowing and saving, and multiplicative shocks to utility.
Parameters
----------
solution_next : ConsumerSolution
The solution to the succeeding one period problem.
IncomeDstn : [np.array]
A list containing three arrays of floats, representing a discrete
approximation to the income process between the period being solved
and the one immediately following (in solution_next). Order: event
probabilities, permanent shocks, transitory shocks.
PrefShkDstn : [np.array]
Discrete distribution of the multiplicative utility shifter. Order:
probabilities, preference shocks.
LivPrb : float
Survival probability; likelihood of being alive at the beginning of
the succeeding period.
DiscFac : float
Intertemporal discount factor for future utility.
CRRA : float
Coefficient of relative risk aversion.
Rboro: float
Interest factor on assets between this period and the succeeding
period when assets are negative.
Rsave: float
Interest factor on assets between this period and the succeeding
period when assets are positive.
PermGroGac : float
Expected permanent income growth factor at the end of this period.
BoroCnstArt: float or None
Borrowing constraint for the minimum allowable assets to end the
period with. If it is less than the natural borrowing constraint,
then it is irrelevant; BoroCnstArt=None indicates no artificial bor-
rowing constraint.
aXtraGrid: np.array
Array of "extra" end-of-period asset values-- assets above the
absolute minimum acceptable level.
vFuncBool: boolean
An indicator for whether the value function should be computed and
included in the reported solution.
CubicBool: boolean
An indicator for whether the solver should use cubic or linear inter-
polation.
Returns
-------
None
