Implementing Tourguide for issue #28

[litenull]

This looks good in general.

Some comments:

1. Why do we need sass if we have styled components?
2. Put default values in variables instead of hard coding

Overall looks good, a bit of a nitpick - would prefer if we use ID instead of class since we want to ensure the components going on tour is unique, but this one works too
