Choose the most specific method when calling overloaded methods

[lukaseder]

Currently, jOOR chooses the "first" matching method if multiple overloaded methods are applicable. E.g.:

void method(Object o);
void method(Number o);
void method(Integer o);

// This should call method(Number), but it may also call method(Object)
on(Test.class).create(new Long("1"));

Finding the most specific method according to the rules of the JLS is not easy, in particular because jOOR follows its own rules. E.g., in the future, we may also want to consider private methods to be eligible for the search algorithm.
