While implementing the Go driver, I've noticed there is no specifications for cursors, either pre-3.2 and post-3.2. We should have a specification for Cursor that covers both the find/getMore/killCursors spec way of doing cursors and the 3.0 OP_QUERY/OP_GET_MORE/OP_KILL_CURSORS way of doing cursors.

The main reason for documenting the pre 3.2 functionality is so that new engineers have a reference for implementations in their code.
