I do not feel like introducing this new dependency brings many benefits. Please explain why this change is needed.

Hey, in my case of testing i have many seed classes and to run them specific for particular test to really speed up the test suite.
Why should i run complete DatabaseSeeder if i only need a couple of them. And because it may be more than one seed class it would be great to run them in one function that accept also an array.
