=head1 PURPOSE
Type library used in several test cases.
Defines types C<SmallInteger>, C<BigInteger> and C<Distance>.
Defines classes C<Foo::Bar> and C<Foo::Baz> along with correponding
C<FooBar> and C<FooBaz> class type constraints; defines role C<Quux>
and the C<DoesQuux> role type constraint.
Library extends DemoLib.pm.
