Group class structure

[jameslkingsley]

The current group class structure is a bit long and it could be a pain to expand it in the future. There needs to be a very efficient way of structuring the groups so that we have a universal class to be used in the platoon roster, comm plan, map markers etc. I'm not too sure how to properly structure this since I don't really want to have hard coded groups since adding groups in the future would be a lot of work and if a mission maker wants a custom group that's not there it could be quite difficult for them to implement.

Are you talking about GrpNATO_XX structure? Personally don't see a more efficient way of doing it since all groups need unique identifiers.

No that's the part which is fine, it's how you sort those groups for roster and stuff. Look at my latest commit it should show a group class with some stuff.
