Generate an entry point for generated Assert classes (like Assertions)

[joel-costigliola]

There is an example of such class in assertj-examples:

 // extending make all standard AssertJ assertions available.
public class MyProjectAssertions extends Assertions {

  // add the custom assertions related to MyProject

  public static TolkienCharacterAssert assertThat(TolkienCharacter actual) {
    return new TolkienCharacterAssert(actual);
  }

  public static HumanAssert assertThat(Human actual) {
    return new HumanAssert(actual);
  }

  public static EmployeeAssert assertThat(Employee actual) {
    return new EmployeeAssert(actual);
  }

  public static EmployeeOfTheMonthAssert assertThat(EmployeeOfTheMonth actual) {
    return new EmployeeOfTheMonthAssert(actual);
  }

}
