Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method, *args, &block) ⇒ Object

Any method missing on this class is delegated to the UserSet objects array so that the developer can easily execute any Array method on the UserSetRelation

Examples:

user.sets.each ....     => Iterate through the UserSet objects array
user.sets.size          => Get the size of the UserSet objects array
