Bug/example missing semicolon (#5)

Fixes example bug that didnt get caught by travis CI

New example added in previous PR had a missing semicolon.
That went in because building that example wasn't part of the required automation bits.
This PR fixes the semicolon and adds that to the automation/Build list.
