Base inflation-coupon pricer.
The main reason we can't use FloatingRateCouponPricer as the base is that it takes a FloatingRateCoupon which takes an InterestRateIndex and we need an inflation index (these are lagged).
The basic inflation-specific thing that the pricer has to do is deal with different lags in the index and the option e.g. the option could look 3 months back and the index 2.
We add the requirement that pricers do inverseCap/Floor-lets. These are cap/floor-lets as usually defined, i.e. pay out if underlying is above/below a strike. The non-inverse (usual) versions are from a coupon point of view (a capped coupon has a maximum at the strike).
We add the inverse prices so that conventional caps can be priced simply.
