Counting the number of times that code is executed

The CountAllIterations class counts the number of times code is executed by all virtual users. The CountUserIterations class counts the number of times code is executed by an individual virtual user.

The CountAllIterations class counts the number of times it is executed by all virtual users running in a particular JVM and returns this count as a string.

 * JVM (as would typically be the case), this class will count the number of
 * times it is run on the agent.
