Thanks for vtlib, Prasad.

I'm debugging some code that will speed up module 
development with vtlib. It's 2 new classes, Installer 
and CustomModule. They're basically abstractions of 
the code in the vtlib 2.1 Payslip example. With them 
I was able to write a new custom module and installer 
in about 200 lines total.

Still some bugs, but if anyone wants to get started 
on a potentially much easier path, let me know.
