-- table library extensions

-- allows the table.copy function to return a shallow copy of a range of the table items
-- Example:
--local t={1,2,3,4,5,6,7,8,9,10}
--dump(table.copy(t,3,8))
--prints out 3,4,5,6,7,8
local table_copy = table.copy
table.copy = function( t, ... )
	if (type(arg[1]) == "number" and (arg[2] == nil or type(arg[2]) == "number")) then
