If I know I want to create a new Person named jim, it's a huge pain to get a handle on this entity.

What I would like to do:

entity = dataset.entity(['Person', 'jim'])
entity['age'] = 80
entity.save()

What I currently have to do:

key = Key.from_path(['Person', 'jim']).dataset(dataset)
entity = dataset.entity('Person').key(key)
entity['age'] = 80
entity.save()

This is a whole bunch of extra wiring I really shouldn't need to deal with.
