Begin Transition to Vuejs

[AABoyles]

After two false starts with React and getting tied up in the absurd toolchain it drags along with it, I've begun to suspect that Vue is the best candidate for managing MicrobeTrace's DOM.

This ticket is less of an explicit Todo than a flag that I'll resolve whenever I get the first Vue-based widget standing. However, I have not explicit plans about which widget that should be, so watch this space.
