Can we use the encoding/csv package?

[stelgenhof]

I wanted to be accurate and ensure that string fields are always quoted, since URL's technically can have comma's (as per RFC 3986). For example in the query string. My first attempt was actually using the encode/csv package, however read somewhere that it doesn't quote by default or otherwise quote every field, so opted for this approach.

However, after some more reading, I think my understanding may have been wrong and can actually use the encoding/csv instead. I'll do some refactoring 😄
