Artificial datasets for non-stationary streaming classification task

Archive of simulated non-stationary data for streaming classification task.
Two generic non-stationary processes considered:
- step change;
- gradual change.
Case of two forms of periodicity also considered
- repeated or asymmetric;
- mirrored or symmetrical.
