Single-factor Hull-White (extended Vasicek) model class.
This class implements the standard single-factor Hull-White model defined by [ dr_t = ( heta(t) - lpha r_t)dt + igma dW_t ] where $ lpha $ and $ igma $ are constants.
- calibration results are tested against cached values
- When the term structure is relinked, the r0 parameter of the underlying Vasicek model is not updated.

static Rate convexityBias (Real futurePrice, Time t, Time T, Real sigma, Real a) [static]
Futures convexity bias (i.e., the difference between futures implied rate and forward rate) calculated as in G. Kirikos, D. Novak, 'Convexity Conundrums', Risk Magazine, March 1997.
- t and T should be expressed in yearfraction using deposit day counter, F_quoted is futures' market price.
