+/**
+ * This class is used to test Ndb's ability to handle 
+ * node- and system-restarts.
+ * For example:
+ *  Node restart:         Restart one node in the cluster.
+ *  System restart:       Restart all nodes in the cluster.
+ *  Node crash:           Crash one node in the middle of execution and bring it up again.
+ *  Multiple node crash:  Crash multiple nodes with a few seconds or milliseconds delay between.
+ *  Initial node restart: Restart one node in the cluster without a filesystem on disk.
+ *  
+ * Each restart type is represented by a NdbRestart class and a collection of these are stored 
+ * in the NdbRestarts class.
+ *
+ * This class may be used from other programs to execute a particular restart.
