Detailed Description

Wrapper that creates a yoy from a zc index.

This creates a "ratio" - type YoYInflationIndex with the same family name as the zero index so that historical fixings can be reused. If a yoy ts is given, this is used to forecast fixings. If the ts is not given, the forecast falls back on the zero index, i.e. if the zero index has a curve attached a plain yoy rate without convexity adjustment is estimated using this index. The interpolation follows

• the interpolated flag for historical fixings
• the interpolated flag for forecasted fixings if a yoy ts is given
• the underlying zero index behaviour for forecasted fixings if no yoy ts is given
