Detailed Description

Swaption cube that combines an ATM matrix and vol spreads from a cube.

Notice that the TS has a floating reference date and accesses the source TS only via their time-based volatility methods.

Warning:

the given atm vol structure should be strike independent, this is not checked

the given cube must provide smile sections that provide an ATM level
