Part of our daily routine at Adikteev consist in efficiently
processing time series of interest to us.  This process may
involve computing local information within a rolling time
window of length TAU, such as the number of points in the
window, the  minimum or maximum, or the rolling sum.

An example is given below,  with TAU = 60 and
  •   Time: number of seconds since epoch
  •   Value: price in EUROS
  •   N_O: number of observation of in the curing
      sliding time window
  •   Roll_Sum: the current rolling sum,
  •   Min_Value and Max_Value the minimum/maximum in the
      current window:


   Time       Value N_O Roll_Sum Min_Value Max_Value

We would like you to implement a small program,
which given as an input a file of lines consisting
in one timestamp and one value, will produce a table
similar to the one above.
