Elaborate on current training materials and tailor for broader use

[dshemetov]

The current long-form epiprocess and epipredict examples focus on individual topics and subsets of functions in some detail, which may not be ideal for first-time users or a broader audience. We will complement these long-form examples and the current “getting started” guides with more accessible and sequential training materials. We will work with STLT partners to improve and expand package training materials to better address their needs and feedback.

This is a meta-issue that will need to get broken down into subtasks.
