Replacement has length zero #44

The error messages in Shiny have now been "santized", and do not show full error messages. This is good, but then I must find a way to let people know when they messed up. For example, if they indicate a Year of Implementation < Year of first data point, the diff-in-diff model won't run because of singularities in the Post term. Options are:

Let user choose years such in an interval: min(years_in_data)+1 : present
Use a modal window to communicate the error

This error was caused by faulty data, not the app
