class_docstr: RangeFeature is an instance of TSFeature. It computes the data statistics over
  any specified contiguous temporal scope specified by the time range. The length of
  the temporal scope is specified explicitly by the length argument, and the start
  point of the temporal scope is specified by the start argument during the object
  instantiation. Various statistics supported by the current implementations are:
  1. mean/average
  2. min/minimum.
  3. max/maximum
  4. std/standard deviation,
  5. range/value range,
  6. intercept/intercept for linear regression fit,
  7. trend / slope of the linear regression fit,
  8. rsquared / r2 or squared pearson correlation
  9. max_deviation / unsigned maximum change between successive observations.
