Issue in problems/duplexer/problem.txt

This says:

"The duplexer module exports a single function duplexer(writable, readable) that joins together a writable stream and readable stream into a single, readable/writable duplex stream."

... but it should be:

"...a single function duplexer(readable, writable) that joins ..."

You have the arguments flip-flopped.

The correct signature is indeed duplexer(writable, readable), not what you are suggesting. See this.

@yihangho is correct. This should be closed.

Closing as there is also another #127 together with #104
