Add support for grid-based datum transformation.
Applies to all Map Suite .NET developer controls (core enhancement).
Although the PROJ.4 libraries allow grid-based datum transformation through the use of the +nadgrids option, Map Suite's current projection classes do not support this. This enhancement would add core support for this type of datum conversion through the use of a NTv2 grid file (.gsb).
The idea for this enhancement was first raised in this discussion thread.
