	 * The plugin interface works like this:
	 * 1. You place the plugin in the plugins folder named your_thing.php
	 * 2. You implement your test in the function measure_your_thing($config)
	 * 3. If you determine that the test is not available on the running PHP version, platform
	 *    etc, then you return null
	 * 4. Otherwise you return the elapsed time for the test in ms.
	 * 5. In addition if you want to return several counters, then return
	      array('something' => value, 'somethingelse' => value), still in ms.
	 * 6. If you want to log something informationally, then just call log_message("your message")
	 *
	 * See helpers.php for some useful helper functions.
