Basket Loss & LHP Loss Model

Two small comments:

1. In https://github.com/lballabio/QuantLib/blob/master/Examples/BasketLosses/BasketLosses.cpp it says Expected 10-Yr Losses but in fact we have advance(..., Period(60, Months)). And 60 months are 5 years, not 10.

2. In https://github.com/lballabio/QuantLib/blob/master/ql/experimental/credit/gaussianlhplossmodel.cpp the return value of function GaussianLHPLossModel::expectedTrancheLossImpl is not divided by (detachLimit - attachLimit) as should be done, see e.g.
