			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.

Wrapper for lua function ipairs(t):

Used in loop constructs to iterate through the values of a table where there is no index (an array).

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.
