This method accepts a list of array references. Each array reference
should contain a role name as its first element. The second element is
-an optional hash reference. The hash reference can contain C<exclude>
-and C<alias> keys to control how methods are composed from the role.

The return value is a new L<Moose::Meta::Role::Composite> that
represents the combined roles.
Returns true if the role requires the named method.
