-%% Data = string() | io_list()
-%% Headers = string()
-%% Body = io_list()
-%%
-%% Description: Parses <Data> and divides it to a header part and a
-%% body part. Note that it is presumed that <Data> starts with a
-%% string including "\r\n\r\n" if there is any header information
-%% present. The returned headers will not contain the HTTP header body
-%% delimiter \r\n. (All header, header delimiters are keept.)
-%% Ex: ["Content-Type : text/html\r\n Connection : closing \r\n\r\n" |
-%% io_list()] --> {"Content-Type : text/html\r\n Connection : closing \r\n",
-%% io_list()}

-%% Description: Transforms the plain HTTP header string data received
