What's New?
Added Encoder to go along with the Decoder.
Notes
To maximize compatibility with other systems the Encoder attempts
to avoid using array indexes in url.Values if at all possible.
eg.
// A struct field of
Field []string{"1", "2", "3"}
// will be output a url.Value as
"Field": []string{"1", "2", "3"}
and not
"Field[0]": []string{"1"}
"Field[1]": []string{"2"}
"Field[2]": []string{"3"}
// however there are times where it is unavoidable, like with pointers
i := int(1)
Field []*string{nil, nil, &i}
// to avoid index 1 and 2 must use index
"Field[2]": []string{"1"}
