New logo and general design language

With the new hub we hope to build, and the new events we want to run, we would love to bring a new look to the society. We're currently designing a new logo to go along with out first event as the new execs, we would also love to create a design language to be used within the society to aid with the development of any websites, posters, etc.

We will create a repo in sucs/ group to store guidelines and colour palettes. This should also help with the development of micro-services and could also provide some useful templates for anybody planning on building one.
