MarkovFunctional_SwapRateDayCount

BUG
QuantLib may generate the error "year 2200 out of bounds. It must be in [1901,2199]" when a swaption is priced with a MarkovFunctiional model, of which the swap rate has the daycount convention of ACT/360.
In particular this occurs when the last tenor value exceeds the coupon period of the swap rate.
On the technical side, the QuantLib function MarkovFunctional::initialize() generates a huge array of dates in calibrationPoints_, which also contains dates very far in the future that ultimately result in the reported error message.
