 This test needs to be at the root of your Web Server (http://localhost/CPURLConnectionAsyncTest/) and with php enabled.
 For each test, we start 3 async connections and we setup the resulting operations to be dependant one from each other. The connection received after the smallest delay is dependant on a connection received with a longer delay.
    We test that dedendant operations are perfomed before their dependencies.
    We also test that in the completionHandler(response, data, error), the data and error params are mututally exclusive.*/
