ContiPerf full changelog

· warmup time measurement handling fails with custom clock
· client application hangs when finished

Enhancements:
· Using the system's most exact clock by default
· Supporting custom clock implementations
· Supporting multiple different clocks at the same time
Implemented alternative clocks:
· system (the system's clock)
· cpu (the thread's CPU time)
· user (the thread's user time)

Bug fixes:
· NullPointerException in reports during parallel test execution

Bug fixes:
· NullPointerException in reports during parallel test execution

Enhancements:
· Ramp-up time to specify the time to wait before adding a new thread, e.g. @PerfTest(rampUp = 1000)
· Supporting warm-up time to start measurement and requirement checking after an initial time period is over, e.g. @PerfTest(warmUp = 1000)
· Supporting wait timers to induce wait time between invocations
· usage e.g. @PerfTest(timer = RandomTimer.class, timerParams = { 200, 400 })
· predefined timers: None, ConstantTimer, RandomTimer, CumulatedTimer custom timers by implementing the WaitTimer interface
· new method LatencyCounter.percentileAboveLatency(latency) @RunWith(ParallelRunner.class) to execute all tests of a class concurrently Javadoc for tooltip help on @PerfTest and @Requirement
· new method CounterRepository.printSummary()
· Method StopWatch.stop() returns the elapsed time in milliseconds

Bug fixes:
· CSVSummaryReportModule causes FileNotFoundException
· HTML report displays the wrong date
