Support creation of arbitrary ArchConditions from Predicates

[u3r]

Hi everyone,

internally there are already DoesConditionByPredicate, IsConditionByPredicate, HaveConditionByPredicate. What is missing is access to them, e.g. in the form of

// ArchCondition.java
public <T extends HasDescription & HasSourceCodeLocation> ArchCondition<T> have( DescribedPredicate<T> predicate ) {
    return new HaveConditionByPredicate(predicate);
}

public <T extends HasDescription & HasSourceCodeLocation> ArchCondition<T> is( DescribedPredicate<T> predicate ) {
    return new IsConditionByPredicate(predicate);
}

public <T extends HasDescription & HasSourceCodeLocation> ArchCondition<T> does( DescribedPredicate<T> predicate ) {
    return new DoesConditionByPredicate(predicate);
 }

as well as the respective shortcuts in ClassesShould, ClassesShouldConjuntion, MethodsShould, MethodsShouldConjunction .... e.g.

/*IsConditionByPredicate*/ ClassesShould.be(DescribedPredicate<T> predicate)
/*HaveConditionByPredicate*/ ClassesShould.have(DescribedPredicate<T> predicate)

this would make writing own Archrules (by using mainly predicates) so much easier and more general.
