JOSS Review: Observe events for submit buttons

[elimillera]

This is related to #4 . Not necessarily something that should hold up a review, just a recommendation.

In several places input$submit > 0 or is.null(input$submit) is used. If you are only looking to update the displays when a submitting button is pressed, the shiny::observeEvent function would be the solution to that. You could wrap the derivation of tables and plots in that to only have the outputs change on a update to input$submit. Right now the application is reactive when the submit button has been pressed but not otherwise.
