+ * We use a Least Mean Squares filter to smooth out the output of the yaw
+ * sensor.
+ *
+ * The goal is to estimate the output of the sensor based on previous acquired
+ * samples.
+ *
+ * We approximate the input by a line with the equation:
+ * Z(t) = a * t + b
+ *
+ * We use the Least Mean Squares method to calculate a and b so that the
+ * distance between the line and the measured COUNT inputs Z(t) is minimal.
+ *
+ * In practice we only need to compute b, which is the value we're looking for
+ * (it's the estimated Z at t=0). However, to improve the latency a little bit,
+ * we're going to discard a certain number of samples that are too far from
+ * the estimated line and compute b again with the new (trimmed down) samples.
+ *
+ * notes:
+ * 'a' is the slope of the line, and physicaly represent how fast the input
+ * is changing. In our case, how fast the yaw is changing, that is, how fast the
+ * user is spinning the device (in degre / nanosecond). This value should be
+ * zero when the device is not moving.
+ *
+ * The minimum distance between the line and the samples (which we are not
+ * explicitely computing here), is an indication of how bad the samples are
+ * and gives an idea of the "quality" of the estimation (well, really of the
+ * sensor values).
