rounds_preference intent DailyRounds Assistant

rounds_preference.js

/**
* This handles when the user has said his/her speciality preference.
* This intent can be reached either from 'cases' intent (cases-followup context),
* when the speciality preference hasn't been mentioned and assistant asks for it.
* Or, when the user says 'Change my speciality preference'.
*
* In the first case, 'cases-followup' context has exhausted only 1 lifespan until now,
* i.e., in answering "Yes" for the question "Would you like us to save your preference?".
* So, when 'cases-followup' context exists, it means that it has come from the initial
* intent of "Latest 10 cases" and so, we need to proceed with fetching the cases after
* saving the speciality preference.

* If 'cases-followup' context doesn't exist means it has come from the second case,
* where we just save the speciality preference and show him suggestions.
