-	'''Return the moving averages of the data, with a window size of
-	`subset_size`.  `subset_size` must be an integer greater than 0 and
-	less than the length of the input data, or a ValueError will be raised.
-
-	`data_is_list` can be used to tune the algorithm for list or iteratable
-	as an input.  The default value, `None` will auto-detect this.
-	The algorithm used if `data` is a list is almost twice as fast as if
-	it is an iteratable.
-
-	`avoid_fp_drift`, if True (the default) sums every sub-set rather than
-	keeping a "rolling sum" (which may be subject to floating-point drift).
-	While more correct, it is also dramatically slower for subset sizes
-	much larger than 20.
-
-	NOTE: You really should consider setting `avoid_fp_drift = False` unless
-	you are dealing with very small numbers (say, far smaller than 0.00001)
-	or require extreme accuracy at the cost of execution time.  For
-	`subset_size` < 20, the performance difference is very small.
