[OSRS-PROJ] NTv2 (.gsb) grid shifting support

[Paul Selormey]

Hello Frank,
Since Proj4 is a working code being used in many applications,
I think it will be better to commit only working codes.

Not everyone will read this, and some may even join the list
later. In fact, you do not have to join the list to use the Proj4 :((

Best regards,
Paul.
