+ *
+ * Options
+ *  - **skip** {Number} skip number of documents to skip.
+ *  - **limit** {Number}, limit the number of results to return. -1 has a special meaning and is used by Db.eval. A value of 1 will also be treated as if it were -1.
+ *  - **sort** {Array | Object}, set to sort the documents coming back from the query. Array of indexes, [['a', 1]] etc.
+ *  - **hint**  {Object}, hint force the query to use a specific index.
+ *  - **explain** {Boolean}, explain return the explaination of the query.
+ *  - **snapshot** {Boolean}, snapshot Snapshot mode assures no duplicates are returned.
+ *  - **timeout** {Boolean}, timeout allow the query to timeout.
+ *  - **tailable** {Boolean}, tailable allow the cursor to be tailable.
+ *  - **awaitdata** {Boolean}, awaitdata allow the cursor to wait for data, only applicable for tailable cursor.
+ *  - **batchSize** {Number}, batchSize the number of the subset of results to request the database to return for every request. This should initially be greater than 1 otherwise the database will automatically close the cursor. The batch size can be set to 1 with cursorInstance.batchSize after performing the initial query to the database.
+ *  - **raw** {Boolean}, raw return all query documents as raw buffers (default false).
+ *  - **read** {Boolean}, read specify override of read from source (primary/secondary).
+ *  - **slaveOk** {Boolean}, slaveOk, sets the slaveOk flag on the query wire protocol for secondaries.
+ *  - **returnKey** {Boolean}, returnKey only return the index key.
+ *  - **maxScan** {Number}, maxScan limit the number of items to scan.
+ *  - **min** {Number}, min set index bounds.
+ *  - **max** {Number}, max set index bounds.
+ *  - **showDiskLoc** {Boolean}, showDiskLoc show disk location of results.
