When I embed a document it appears to add an _id column to the
document. Is there a way to disable this behavior?
For instance, this example:
>> person = Person.new
>> person.phone_numbers.build(:number => "415-555-1212")
>> #<Phone _id: 4d978f8c5626cd1c0b000006, _type: nil, _id: BSON::ObjectId('4d978f8c5626cd1c0b000006'), number: "415-555-1212">
There's no reason to have this in the document and I don't want it in
there. If I make a field an array or a hash I can avoid this. However,
I want it to be an object.
