EPIC UX to run simulation calculation

[Br3nda]

As a user, i want to set the value of several variables (for a period of time DAY, MONTH, YEAR), and then pick which different variable i want calculated, and tell RAputure to talk to Open Fisca and run the simluation.

e.g.
i want to set rates_rebates__combined_income, rates_rebates__dependants, and rates_rebates__rates_total for a YEAR, and then run a simulation what gives me the calculate value of rates_rebates__rebate for that same YEAR.

Here's some initial UI. There's some feature stories resulting from it.
