## Detailed Description

Constant local volatility, no time-strike dependence.

This class implements the LocalVolatilityTermStructure interface for a constant local volatility (no time/asset dependence). Local volatility and Black volatility are the same when volatility is at most time dependent, so this class is basically a proxy for **BlackVolatilityTermStructure**.
