Intro to CUFSM

In 2017 for my course on structural stability I provided a 10 minute video introduction to CUFSM 4.5. That version uses the same interface as version 5.04 today and thus provides a workable first introduction to CUFSM for those interested in cross-section elastic buckling analysis using CUFSM. We are working on more up to date content, but this provides a reasonable place to start for now (April 2020).
