     *
     *          "multiple": All documents matching $criteria will be updated. MongoCollection::update has exactly the opposite behavior of MongoCollection::remove- it updates one document by
     *          default, not all matching documents. It is recommended that you always specify whether you want to update multiple documents or a single document, as the
     *          database may change its default behavior at some point in the future.
     *
     *          "safe" Can be a boolean or integer, defaults to false. If false, the program continues executing without waiting for a database response. If true, the program will wait for
     *          the database response and throw a MongoCursorException if the update did not succeed. If you are using replication and the master has changed, using "safe" will make the driver
     *          disconnect from the master, throw and exception, and attempt to find a new master on the next operation (your application must decide whether or not to retry the operation on the new master).
     *          If you do not use "safe" with a replica set and the master changes, there will be no way for the driver to know about the change so it will continuously and silently fail to write.
     *          If safe is an integer, will replicate the update to that many machines before returning success (or throw an exception if the replication times out, see wtimeout).
     *          This overrides the w variable set on the collection.
     *
     *         "fsync": Boolean, defaults to false. Forces the update to be synced to disk before returning success. If true, a safe update is implied and will override setting safe to false.
     *
     *         "timeout" Integer, defaults to MongoCursor::$timeout. If "safe" is set, this sets how long (in milliseconds) for the client to wait for a database response. If the database does
     *         not respond within the timeout period, a MongoCursorTimeoutException will be thrown
