This entails: - Changing the current structure to have a single timestep (summary bin in this case) in each row of a tibble - Adding a null_probability list that includes a vector of null probability results - renaming/updating the event probabilities to: event_probability(_positive, _negative, _either, _both) - extending null_probability to include: null_probability(_positive, _negative, _either, _both) - appending lipd tibble metadata to each row.
