move delays and transmission episodes to tutorials-middle repo

[avallecam]

Aim: evaluate concept connectivity between: access delays, quantify transmission, use delays episodes, with the next epinow2 release

• from time periods to delays and extract single delays
• delay interface to quantify transmission (extend on uncertainty for each summary statistic)
• use delays in analysis (to quantify transmission whole and stratified analysis)
• delay distribution functions (to connect with estimate severity and simulate transmission chains)

(in callouts, highlight the usefulness of epiparameter interface)

whole workshop rearrangement proposal

Link	Early task	Middle task	Late task
Task	Reading and cleaning case data	Real-time analysis and forecasting	Scenario modelling
	Read, clean, and validate linelist data. Transform to incidence data and describe case distribution.	Read contact data to estimate superspreading and simulate transmission chains.	Read a social contact matrix to simulate disease spread and investigate interventions.
	Access delay distributions and estimate transmission metrics.	Read incidence data to forecast cases and estimate severity.	Estimate the final size to compare economic impacts.
