- * suggest - generates a suggestor function to be used by emoji-input
- * data: object providing source information for specific types of suggestions:
- * data.emoji - optional, an array of all emoji available i.e.
- * (state.instance.emoji + state.instance.customEmoji)
- * data.users - optional, an array of all known users
- * updateUsersList - optional, a function to search and append to users
- *
- * Depending on data present one or both (or none) can be present, so if field
- * doesn't support user linking you can just provide only emoji.
