Central Moving Average noise removal
The 'central_moving_averages' function takes a smoothing distance and an
array reference and returns a list that averages all values in the input
over the distance value, in other words, it returns for each value in the
input the arithmetic mean of that value plus $distance many values before
and $distance many values after it. A practical application would be
smoothing time series data.
