printing on console when data is sent to parent
minor console.log string change
checking user-agent on request

- added a middlware that will run in every request and should check
from which type of user agent the request has been sent to us.
- simplified the “riob.us/busLine” rout
- changed code on “riob.us/?busLine” rout to look more like the
approach that we will need to use to accept more than one bus line on
the request
