CommandCursor class to iterate over command results.
Create a new command cursor.
Does this cursor have the potential to return more data?
Limits the number of documents returned in one batch. Each batch requires a round trip to the server. It can be adjusted to optimize performance and limit data transfer.
Note
batch_size can not override MongoDB’s internal limits on the amount of data it will return to the client in a single batch (i.e if you set batch size to 1,000,000,000, MongoDB will currently only return 4-16MB of results per batch).
Raises TypeError if batch_size is not an integer. Raises ValueError if batch_size is less than 0.

Explicitly close / kill this cursor. Required for PyPy, Jython and other Python implementations that don’t use reference counting garbage collection.

Advance the cursor.
