module WhitelistMatcher 
  # Checks if all of the specified attributes are mass-assignable, and if all the others are protected.
  # If used with should_not, then ONLY the specified attributes should be protected from mass assignment, and for all other it should be allowed 
  #      (i.e. behavior similar to :except )
  # It also supports roles by chaining as()
  #
  # it { should whitelist(:email, :password, :password_confirmation) }
  # it { should_not whitelist(:admin, :balance)
  # it { should whitelist(:owner).as(:superuser)
