u'''(INTERNAL) Classes C{_Named}, C{_NamedDict} and C{_NamedTuple}, 

all with nameable instances and several subclasses thereof. 

 

In addition, the items in a C{_NamedDict} are accessable as attributes 

and the items in a C{_NamedTuple} can be named to be accessable as 

attributes, similar to standard Python C{namedtuple}s. 

 

Results previously returned as tuples by C{pygeodesy} functions and 

class methods are now instances of some C{...Tuple} class, all 

sub-classes of C{_NamedTuple} defined here.
