34 /*! This is the abstract base class that encapsulates the notion of a
35 product: it contains the information that would be in the termsheet
36 of the product.
37
38 It's useful to have it be able to do several products simultaneously.
39 The products would have to have the same underlying rate times of
40 course. The class is therefore really encapsulating the notion of a
41 multi-product.
42
43 For each time evolved to, it generates the cash flows associated to
44 that time for the state of the yield curve. If one was doing a
45 callable product then this would encompass the product and its
46 exercise strategy.
