-Corrected bug while setting the frequency of the first step: was using
a step duration of 1ms instead of the intended 1s;
-Discovered a bug in the SLI where an invalid resize (to 19, 16, I
believe) would occur. Still not corrected;
-Added a new method to generate readings to obtain an intended alpha and
beta values for AutoGait, in the OfflinePositioning tester;
