Vi = V(i-1)*(1+r) - Di + Si
Where Vi = Investment value in year i, Di = Distribution in year i, and Si = Savings in year i
Di = DV/(1-t) if fixed amount distribution of DV and t is tax rate
Di = Vi * DF/(1-t) if fixed percentage of investment value of DF
Di is set to Vi*RMD_rate if that is higher than Di computed above and RMD is enabled.
Fixed distribution and savings are scaled for inflation if inflation_adjusted option is checked
Default retirement income on slider is set to investment return rate if variable, or
invest value at beginning of retirement times (investment return_Rate - inflation_rate).
