2.2.0

• Enhancement
  • Including Classification S-Learner model to the causal cate learning library.
• Bug Fix
  • Fix validator behavior when receiving data containing gaps and a time based split function that
    could generate empty
    training and testing folds and then break.
    The argument drop_empty_folds can be set to True to drop invalid folds from validation and
    store them in the
    log.
• Documentation
  • Including Classification S-learner documentation and changing validator documentation to
    reflect changes.
