This method is used both when an enum class is given a value to match to an enumeration member (i.e. Color(3)) and for the functional API (i.e. Color = Enum('Color', names='RED GREEN BLUE')). When used for the functional API: `value` will be the name of the new class. `names` should be either a string of white-space/comma delimited names (values will start at `start`), or an iterator/mapping of name, value pairs. `module` should be set to the module this class is being created in; if it is not set, an attempt to find that module will be made, but if it fails the class will not be picklable. `qualname` should be set to the actual location this class can be found at in its module; by default it is set to the global scope. If this is not correct, unpickling will fail in some circumstances. `type`, if set, will be mixed in as the first base class.
