Bring NXG C Node to LabVIEW

I just found out about LabVIEW NXG's C Node. I know my team would love to have it in LabVIEW to use for bit masking in a familiar syntax. The Expression and MathScripts nodes have issue with 64-bit values and give unexpected results. A quick test in C Node does fix these issues.

As far as bit masking, what is difficult about the AND, OR, and Logical Shift?

U64s did not work properly for values values > 2^31 for the expression node. There seems to be some incorrect casting/assumptions of U32/I32. It would be nice to have this done more inline with the familiar syntax.
