eolian: introduce the keyword required This introduces a new keyword called required. It only works on mixins. You can specify a list of regular/abstract classes in there. Classes specified after the required keyword are later used to verify the usage of the mixin. With this feature a mixin can define a list of types that the inheriting object (the object that inherits from a mixin) needs to fullfill, if one class that is required is not in the implemented classes, then eolian will bail out.
