  We inherit include permissions from previous roles in the same scope (role order)
  To determine role order, we use `roleScopes` object

  So for example ProjectRoles.COMMENTER has `commentEdit` permission,
    which means ProjectRoles.EDITOR, ProjectRoles.CREATOR, ProjectRoles.OWNER will also have `commentEdit` permission
    where as ProjectRoles.VIEWER, ProjectRoles.NO_ACCESS will not have `commentEdit` permission.

  This is why we are validating that there are no duplicate permissions within the same scope
    even though it is not required for the code to work. It is to keep the code clean and easy to understand.
