Overview

A NonConvertingFactory accepts objects that are already native, and throws a mismatch error for anything else.

Examples:

ff = Gorillib::Factory::NonConvertingFactory.new(:product => String, :blankish => ->(obj){ obj.nil? })
ff.receive(nil)    #=> nil
ff.receive("bob")  #=> "bob"
ff.receive(:bob)   #=> Gorillib::Factory::FactoryMismatchError: must be an instance of String, got 3
