Editing WoW:API ipairs

{{luaapi}}
Returns an iterator triple that allows the Lua for loop to iterate over the array portion of a table.
 iteratorFunc, table, startState = ipairs(table)

== Example ==
 local fruits={"apple","orange","banana","kiwi"}

 for index,value in ipairs(fruits) do 
   DEFAULT_CHAT_FRAME:AddMessage(tostring(index).." : "..value)
 end

Result:

  1 : apple
  2 : orange
  3 : banana
  4 : kiwi

would be output to the chat window.

Note that ipairs() starts at index 1 and stops counting as soon as it reaches a nil value. Example:

 > t = { [0]      = "zero",   --will not be counted
         [1]      = "one",    --will be counted; 1
         [2]      = "two",    --will be counted; 2
         [3]      = "three",  --will be counted; 3
         ["four"] = "four",   --will not be counted; returns 3
         [5]      = "five" }  --will never be reached
 > for i,v in ipairs(t) do print(i..":"..v) end
 1:one
 2:two
 3:three

Note that t[0] is never reached because it starts counting at [1], t["four"] is never reached because it is not an array index, and t[5] is never reached because the iterator ceases when it checks t[4] and finds a nil value.
