Validate inputs #41

Closed jemus42 closed 8 years ago

Many fields need to have a value set, i.e. not empty. So when entering a value, one might clear the input cell, causing a mess in the console, which many users will probably find concerning.

I assume the solution would be to pipe input elements through shiny::validate to make sure they're not empty and the theme receives valid input.
