soProvides a factory class for generating dynamic messages.

The easiest way to use this class is if you have access to the FileDescriptor
protos containing the messages you want to create you can just do the following:

message_classes = message_factory.GetMessages(iterable_of_file_descriptors)
my_proto_instance = message_classes['some.proto.package.MessageName']()

    Passing a descriptor with a fully qualified name matching a previous
    invocation will cause the same class to be returned.

    Args:
      descriptor: The descriptor to build from.

    Returns:
      A class describing the passed in descriptor.

W|S(s�Gets all the messages from a specified file.

    This will find and resolve dependencies, failing if the descriptor
    pool cannot satisfy them.

    Args:
      files: The file names to extract messages from.

    Returns:
      A dictionary mapping proto names to the message classes. This will include
      any dependent messages as well as any messages defined in the same file as
      a specified message.
