/**
 * Create Snapshot Action Sample
 * Create a snapshot of the volume identified by volume ID. A volume does not have to be detached
 * at the time the snapshot is taken.
 * Important Note:
 * Snapshot creation requires that the system is in a consistent state.
 * For instance, this means that if taking a snapshot of a database, the tables must
 * be read-only locked to ensure that the snapshot will not contain a corrupted
 * version of the database.  Therefore, be careful when using this API to ensure that
 * the system remains in the consistent state until the create snapshot status
 * has returned.
 *   
 * @param Amazon_EC2_Interface $service instance of Amazon_EC2_Interface
 * @param mixed $request Amazon_EC2_Model_CreateSnapshot or array of parameters
