Generates the elements of the tuple in sequence instead of pulling the entire thing into a list.

Also replaces any instances of immediate iteration over the elements with iterating over the generator instead.

Previously, equality was checked by equality of name_to_index dict (IE equality as dicts, as unordered sets of key-value pairs), while hash was generated by iterating over the dict (where order matters).

Since dicts are unordered, it is an implementation detail of the underlying Python whether equality as AnonymousTuples then implies equality of hashes. This is not quite in line with the python spec of hash, which states that objects which compare as equal *must* return the same hash value.

Previously this had to be constructed every time to_elements was called;
now attached to the anonymous tuple itself, and without adding extra iteration over the element array.

Adds a utility to recursively convert AnonymousTuples to an arbitrary container type, and uses this to add a recursive kwarg to AnonymousTuple._asdict for returning a nested structure of OrderedDicts.

Add an _asdict method to AnonymousTuple. This should allow us to avoid importing anonymous_tuple in places where we need to convert the result of a federated comutation back into a standard Python container.

Preserve the order of variable lists and provide ModelWeights.keras_weights, and add methods to convert (keras model weights) <--> (tff model state).

This lets us get back from a ModelWeights structure to a list that can be used with keras_model.set_weights().

Fixes a bug where anonymous_tuple.flatten was used together with nest.pack_sequence_as, which happened to work before but didn't after the other changes in this CL. Consolidates all the TFF-specific code in optimizer_utils.py to a single function.

Raise a ValueError if someone tries to construct an AnonymousTuple with duplicated names, and also check to this when construct OrderedDicts of variables.

Implements federated evaluation (also adds recursive conversion to anonymous tuples from containers, and picks up a few changes to api_docs on rebuild).

- compute hash lazily, but store the computation
- change field name mapping to use dict type
- add __slots__ for the three instance attributes to prevent unused __dict__

Adds an interface for ingesting arguments to allow sequences and federated types Adds an interface for ingesting arguments to allow sequences or federated types to be passed as arguments into the reference executor as plain Python lists and unplaced Python values.

Make source be python 2 and 3 compattble:
  - xrange -> six.moves.range
  - __builtin__ -> six.moves.builtins
  - dict.iteritems() -> six.iteritems(dict)
  - Iterate over dict.values() views to avoid indexing
  - str -> six.b(str) to wrap strings in bytes
  - raise ValueError -> raise AttributeError when accessing a property that does not exist on the object
  - hoist variable declaration out of try/catch block
