/**
* 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.
