This class represents the authorizations for an action. It's associated to a
label, a description, the bit in which flags are saved, and obviously the
authorization array which is encapsulated in the RolesAuthorizations class. The
bit which is used to store the authorization is 2n where n is the
number of the place you want to use. It's recommanded to begin with 1
(20 = 1) then 2 (21 = 2) then 4 (22 = 4) etc...
