At first there weren't many enums in Volume.h, but the number has been growing, and I'm planning to add one more for regions. To not make Volume.h too large, and to avoid needing to include Volume.h in code that doesn't use volume objects, I'm moving the enums to a new file. I'm also turning them into enum classes while I'm at it.
