 * A system implementing this interface supports a component life-cycle. I.e.
 * such a component may be instructed from the outside to run through several
 * stages from getting started till being destroyed. The valid state changes are
 * mainly as follows:
 * 
 * "start" - "pause" - "resume" - "stop" - "destroy"
 * 

 * For example:
 * 
 * "start" - "pause" - "resume" - "pause" - "resume" - "stop" - "start" -
 * "pause" - "resume" - "stop" - "destroy"
