API IsTalentTrainer

__NOTOC__
Indicates whether target can train talents.
 exists = IsTalentTrainer()
==Parameters==
===Arguments===
:none
== Returns ==
:;exists : Bool - 1 if the target can train talents, or nil otherwise.
== Remarks ==
Unlike the IsTradeskillTrainer() function, this function appears bugged in that calling this function on any target returns 1 regardless of whether the target can train class talents.
== Example ==
 if (IsTalentTrainer()) then 
 DEFAULT_CHAT_FRAME:AddMessage("Target is a talent trainer.")
 else 
 DEFAULT_CHAT_FRAME:AddMessage("Target is not a talent trainer.")
 end
=== Result ===
A message indicating that the target is a talent trainer (because the function always returns 1) is displayed in the default chat frame.
