Easily calculate reliable load orders between objects

class Thing
  include Dependable
end

thing1 = Thing.new
thing2 = Thing.new

thing2.needs thing1

thing2.load_path # => [thing1, thing2]

thing2.dependent_on?(thing1) # true
thing1.dependent_on?(thing2) # false

Ability to return dependency load paths as trees that are collapsed as far as they can be.

A needs B, D
B needs C

would be:

- D
- C
--- B
----- A

The benefit here being that loaders could start down multiple paths without having to wait.
