Unfortunately my math is really rusty. We have a permission system we
are building. The permission go in value from low to high. Personal
being what you are allowed to do with your data, Group is how you can
interact with outher user's data.

Personal - View = 1
Personal - Add/Edit = 2
Personal - Delete = 4
Group - View = 8
Group - Edit = 16
Group - Delete = 32

My question is how do I create a function that I can input the
permission value in (example: 63 for full perms) and the require perm
I'm checking (example 8) have it return a true or false if 8 exists in
63?

Thanks.
