API GetQuestLogIndexByID

Returns the current quest log index of a quest by its ID.
 questLogIndex = GetQuestLogIndexByID(questID)
==Arguments==
:;questID: - Unique identifier for each quest. Used as each quest's URL on database sites such as Wowhead.
==Returns==
:;questLogIndex: - The index of the queried quest in the quest log. Returns "0" if a quest with this questID does not exist in the quest log.
==Example==
This snippet gets the QuestID of the most recently displayed quest in a Gossip frame, then gets the index. Now that we have the index of the quest, we can utilize many of the functions that require a quest index. For example, GetQuestLink() requires a quest index.
 local qID = GetQuestID();
 local qLink = GetQuestLink(GetQuestLogIndexByID(qID));
 print("Here's a link to the quest I'm currently viewing at a quest-giver: " .. qLink);
