add inflation adjustments #25

My sources don't go into great detail about inflation, except in the case of annual effective interest. However, handling general inflation for all the different interest rates (nominal, force, discount, etc.) is another story. It may be a concept worth exploring.

see Vaaler & Daniel 6.2.8 for another example

one possible application would be to allow a parameter in the irr calc of Payments to toggle an inflation-adjusted rate
