The IsEqualToEntity matcher (previously, IsEqualsToEntity) has been
improved to allow property comparison by functional reference to the
getter methods of the properties to compare. Specifically, the
"checkAttribute" methods added allow providing a Function<T, R> as a
getter, where T is the type of the entity to compare and R is the type
returned by the getter method.

This commit adds the JSF project with a web application that allows the
management of owners (by the administrators) and pets (by the owners).
The JSF project includes the functional tests for the owners management
page.

The EAR project only contains a POM that creates an EAR distribution of
the system.

Some test classes have been refactorized for a more consistent use of
the OwnersDataset class and for a simpler test implementation.

This matchers makes the Response status easier to check in tests.

The REST layer has been added but with incomplete tests. Students will
have to complete the tests.

This commit includes an important refactorization regarding tests. Test
classes and datasets have been moved from the "service" project to a new
"tests" project. This way, any project can include this "tests" project
as a dependency in order to have access to these common testing
resources.
