An object common for all the nodes in a Proview
 system.

 The object is configured on the top level in the directory volume.

 In runtime the system object is placed in the SystemVolume below
 the pwrNode hierarchy.

 SystemName is used to identify one ProviewR system
 among others.

 Optional description.

 Specifies the name or notation of a ProviewR system.
 The systemname is used to identify volumes registred for a system
 in the global volumelist.

 In the initial configuration, the system name normally equals
 the project name. Sometimes, at an upgrade or major revision, it is
 a good idea to make a copy, to keep the current state of the project.
 The copy will have a new projectname, but the system name remains the
 same, and identifies the volumes and nodes that belongs to the system.

 Specifies the name of the system group that the system
 is a member of.

 The SystemGroup is used for authorisation in the development
 and operator environment.

 SystemGroups are configured in the User Database.
