Summary: Bug in HullWhiteProcess.cpp

Initial Comment:
The calculation in HullWhiteProcess.cpp of alpha seems wrong to me?

Shouldn't the forwardRate-part in the alpha-formula be calculated from time 0 till time t, instead of calcualting the forwardRate from 0 to 0?

Sincerely,
Jeroen,

I would like to correct my previous statement:

the forwardRate-part in the alpha-formula should be calculated from time t
till time t, instead of calcualting the forwardRate from 0 to 0. We need
the instantaneous forwardRate in this case, at time t.
