VirtualUserScript Class
Implements DataDictionary
Many of the operations (methods) of VirtualUserScript are delegated to the VirtualUser class. Access to the VirtualUser instance can be obtained via the attribute _vu.
Owing to delegation, the methods described in this section can be called directly from within the code of any script class. For example:
pause(2000); // pause this VU for 2000 milliseconds (think time)
writeMessage("My message"); // insert a message in the VU event log
