Detailed Description

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.

This method must be implemented in derived classes. An instance of Observer does not call this method directly: instead, it will be called by the observables the instance registered with when they need to notify any changes.
