+% window - Window a sequnce of arrays in a given dimension
+%
+% window :: seq [[N,M]] -> seq [[N]].
+% window :: seq [[N,M]], L:natural -> seq [[N,L]].
+% window :: seq [[N,M]], L:natural, natural ~'hop size' -> seq [[N,L]].
+%
+% This is just short for windowdata(...)
+% Possible optimisation:
+%    when the span and hop are much less than the input buffer size
+%    and the source data does not have an efficient extract method,
+%    then it is worth caching the source data, ie window(cache(x),...) 
+function Y=window(X,varargin), Y=seq.window(X,varargin{:});
