  * suggest - generates a suggestor function to be used by emoji-input

  * 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.
