+/**
+ * Accepts any node Stream instance and hijacks its "write()" function,
+ * so that it can count any newlines that get written to the output.
+ *
+ * When a '\n' byte is encountered, then a "newline" event will be emitted
+ * on the stream, with no arguments. It is up to the listeners to determine
+ * any necessary deltas required for their use-case.
+ *
+ * Ex:
+ *
+ *   var cursor = ansi(process.stdout)
+ *     , ln = 0
+ *   process.stdout.on('newline', function () {
+ *    ln++
+ *   })
