static variable definitions

[yakra]

Static variables can be defined within a class definition; doesn't have to be later.

Arguments can be cleaned up

Apparently I can only do this with integral types? OK...

• Done for HGEdge format constants
• Waypoint::pi #defined instead
• Arguments has enough non-integral types (strings) that the cleanest solution is to leave as-is.

• Make region_hash a static member of region

WRT the above comment and finding other variables in main or wherever to put in a class, those can be done as I notice them. No need to go searching.

WRT the OP, seems only const values work (search "Constant static members").

• Thus GraphListEntry::num must stay as-is, right?

All items specifically mentioned are addressed, or no-build. Only other thing that matches the OP might be...

• DBFieldlength would be perfect for this. Could do away with the .cpp file entirely. Variables would probably be constexpr (links: demystifying / when to use)?
• To that end, if the HGEdge consts were constexpr, would it compile differently?
