# Helper module including specific functions to handle project hooks.
# Supported events:

# - on_load(): When loaded
# - on_save(): When saved
# - on_add_dataset(dataset): When a dataset is added, with name +dataset+
# - on_unlink_dataset(dataset): When dataset with name +dataset+ is unlinked
# - on_result_ready(result): When any result is ready, with key +result+
# - on_result_ready_{result}(): When +result+ is ready
# - on_processing_ready(): When preprocessing is complete
# Supported hooks:
# - run_lambda(lambda, args...)
