  1. option to force to encode empty table to "[]" 

    Since lua-cjson use table index type to decide what type a lua table is
encoded to, there is no way to encode empty lua type to list.

This patch solves this problem by assigning a special meta-table to an
empty table to force it to be encoded to "[]" instead of "{}":

    setmetatable({},cjson.as_array)
