 Description   

Cursor has a ID() int64 method which seems to serve no purpose, at least not for the end user of the API. 

  I propose to either replace this or add a new method ObjectID() which should return the objectID (_id) of the current/latest element from cursor.  Currently there doesn't seem to me a method to get the objectID unless you create new types with an additional "_id"  field for each result.

Hi themihai,

Currently the ID field returns the server cursor ID for the cursor.

Additionally, since the _id of a document may not be an ObjectID, we cannot have a method that returns the ObjectID. If you want the _id you can retrieve the raw bytes, turn it into a bson.Reader and then Lookup the _id element.
