WLUG meeting

Due to William's presentation on the Godot game engine (https://www.meetup.com/WaikatoLinuxUsersGroup/events/165977142/) being shifted to May, we have a different line-up for this meeting:

• Ian Stewart: dynamic chart creation using LibreOffice on Linux and how it compares to MS Excel on Windows

• Chris O'Halloran: early stages of a BrewPi (http://www.brewpi.com/) setup
