Bug 103181: not-monthly repayment schedules not supported in Mortgage/Loan Druid

As a longtime user, I can tell you that there will be a huge cry of thanks from the user base if you can get the mortgage calculator working better. I know I am not the only user who has either abandoned the scheduled mortgage payment altogether, or who has to change every created transaction after the fact because the calf's are off.
I would ask you to consider checking first on whether you can create a "balance as of date" function, as it seems many mortgage complaints originate from the fact that GnuCash can't do this. With such a function, users would be able to prepayment their loans and GnuCash would still be able to calculate and allocate correctly -- something it cannot currently do.
I've been told this would be complicated, but I toss it out with hope...

So many languages, so little time. ;-)
The function names are the same as the C ones except that words are separated wit '-' instead of '_'.

Most current GnuCash code does not separate the controller and view code. We need to fix that.

The existing examples aren't all that good, especially outside of src/engine and src/libqof/qof.
