Default-density term structure.
This abstract class acts as an adapter to DefaultProbabilityTermStructure allowing the programmer to implement only the defaultDensityImpl(Time)
method in derived classes.
Survival/default probabilities and hazard rates are calculated from default densities.

survival probability calculation
implemented in terms of the default density \( p(t) \) as
\[ S(t) = 1 - \int_0^t p(\tau) d\tau. \]
Implements DefaultProbabilityTermStructure.
Reimplemented in InterpolatedDefaultDensityCurve< Interpolator >.
