Parameters.py should accept year-by-year inflation rates about tax-calculator HOT 4 CLOSED

How about:

calc.inflation_rates = [0.011, 0.022, 0.023] + [0.024]*7

You get an exception if the length of inflation_rates is not the same as budget_years in the Parameters object. You could also do:

rates = [0.011, 0.022, 0.023] + [0.024]*7
calculator(parameters="params.json", records="puf2.csv", inflation_rates=rates)

So, in this case, because the default size fo budget_years is 10, if you specify the rates, it has to be of length 10. Thoughts?

@talumbau The top seems fine for now, although 99% of the time we will just use the defaults values. This is because the inflation rates and the blowup factors are linked (i.e., the records blowup factors are partially determined by the inflation rate, and it doesn't make sense to use different inflation rates for blowing up the tax law parameters from the one that we used to generate the records blowup factors)

A couple of notes:

1. I am now running the calculator locally with default budget_years = 12, so that we can blow up params from 2013 through 2024. We will still only want to report the 10 years 2015-2024. If you don't, I will probably make this update in an upcoming PR.
2. Just a heads up: we may need to modify how the data blowup, reweighting, and param inflation are implemented when we link the tax calculator to a macroeconomic model. Then we will want to be able to give the calculator a new set of blowup factors, weights, and inflation rates each time we increment the year (not just when we set up the calculator.)

I think we need to make the default inflation rates the same as those
Ohara assumes for the data. These seem close to his CPIU numbers, but not
exact.
