Look into shinytest for CI

To help automate review of changes, let's use some sort of continuous integration scheme. A quick Google search gives me shinytest (https://rstudio.github.io/shinytest/articles/ci.html). There may be others, but we should evaluate this to make the application robust and easier to test.
