Order rules by dependencies

[nykolaslima]

Today we have the following problem:

Fixture.of(User.class).addTemplate("valid", new Rule() {{
add("email", "${name}@gmail.com");
add("name", random("nykolas", "otavio"));
}};

The above code fails because email depends on name but when email is evaluated, name was not evaluated yet.

@Tavio has solved this problem on Angular-Fixture-Factory(https://github.com/Tavio/angular-fixture-factory) project using Topological sort(http://en.wikipedia.org/wiki/Topological_sorting)
https://github.com/Tavio/angular-fixture-factory/blob/master/angular-fixture-factory.js#L264-L312

We can use the same approach here.

This issue shouldn't be closed? @nykolaslima

And could you generate a new version with the PR #77?

This is indeed already merged via #77
