Shows the state of the c-space. The states are Enabled or Disabled and Started or Shut Down. Note that any combination of Enabled/Disabled and Started/Shut Down is possible, as explained in the following description of each state:

Enabled. The c-space is accepting new conversations (if started).
Disabled. The c-space is not accepting new conversations, but if the c-space is started (running) any existing conversations will be allowed to complete.
Started. The c-space is activated and running on the c-hub. If it is also enabled, it is accepting new conversations. If it is disabled, it is not excepting new conversations.
Shut Down. The c-space is not running. Any previously existing conversations were terminated.
