This routine calculates the synchronisation index (vector strength) from the process EarObject's input signal. It expects its input to come from a period histogram (see section Analysis_Histogram: page 73). The results are set the first sample of the output signal for each respective channel.

This function indicates the ability of a system to follow the periodicity of a stimulus. (see Hewitt and Meddis ??)
