Returns the values in a consecutive-integer indexed table

```ret1, ret2, ... retN = unpack(table[, start [, end]])
```

Will not return values with hash style indexes. For example:

```local t = {1, "two", "3", x = "ecks", y = "why?"}
unpack(t) -- returns: 1, "two", "3"
```

Arguments

table
(table) - A table
start
Integer - Starting index, defaults to 1 if nil
end
Integer - Ending index, appends nil values if the table does not contain enough

Returns

ret1, ret2, ... retN
A list of the values contained in the given table.

Examples

```local arg1, arg2, arg3 = unpack({1, 5, "Hearthstone"})

-- This does the same thing:
local arg1, arg2, arg3 = 1, 5, "Hearthstone"
```
```unpack({1,2,3,4,5},2,7)  -- returns 2, 3, 4, 5, nil, nil
```

Notes

unpack() doesn't return all the values in the following example because it is not a contiguous table.

``` -- Notes Example 1
t = {1,nil,"something",nil}
print(unpack(t))  -- prints 1
```

A simple fix would be to add a value at the end of the list. This works because when you assign a table in this manner, Lua treats it as a contiguous table as long as there is a value at the last index. Nuking this value before adding new values at the end will break this behavior.

``` -- Notes Example 2
t = {1,nil,"something",nil,1}
print(unpack(t))  -- prints 1 nil "something" nil 1
t[5] = nil
print(unpack(t))  -- prints 1
```

If you assign each value individually, unpack() will behave the same way it does in Notes Example 1.

``` -- Notes Example 3
t = {}
t[1] = 1
t[2] = nil
t[3] = "something"
t[4] = nil
t[5] = 1
print(unpack(t))  -- prints 1 even though it's the same contents as in Notes Example 2.
```
