v0.3.2

Fixed

• Improved caching of lower-bound for DTW
  The DTW subsequence search implementation has been improved by caching
  DTW lower-bound information for repeated calls with the same
  subsequece. This slightly increases the memory requirement, but can
  give significantly improved performance under certain circumstances.

• Allow shapelet information to be extracted
  A new attribute ts_info is added to Shapelet (which is accessible
  from tree.root_node_.shapelet). ts_info returns a tuple
  (ts_index, ts_start, length) with information about the index (in
  the x used to fit, fit(x, y), the model) and the start position of
  the shapelet. For a shapelet tree/forest fit on x the shapelet in a
  particular node is given by x[ts_index, ts_start:(ts_start + length)].
