def get_probes_results(self):
raise NotImplementedError<EOL>
Returns a dictionary with the results of the probes.
The keys of the main dictionary represent the name of the probes.
Each probe consists on multiple tests, each test name being a key in the probe dictionary.
A test has the following keys:

    * target (str)
    * source (str)
    * probe_type (str)
    * probe_count (int)
    * rtt (float)
    * round_trip_jitter (float)
    * current_test_loss (float)
    * current_test_min_delay (float)
    * current_test_max_delay (float)
    * current_test_avg_delay (float)
    * last_test_min_delay (float)
    * last_test_max_delay (float)
    * last_test_avg_delay (float)
    * global_test_min_delay (float)
    * global_test_max_delay (float)
    * global_test_avg_delay (float)
