Counting the number of times that code is executed

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.

import com.ibm.rational.test.lt.kernel.services.ITestExecutionServices;

/**
 * The CountAllIterations class counts the number of times it is executed

 * as a string.  If all virtual users on an agent are running in the same
 * JVM (as would typically be the case), this class will count the number of
 * times it is run on the agent.
