Making outbreak analysis easier and prettier

This micro-hackfest was dedicated to designing web-based graphical user interfaces (someone said 'shiny'?) for RECON packages. We focussed on facilitating the user experience, by defining some sort of standard look-and-feel, and on facilitating the development of these interfaces. In a nutshell, outcomes include:

• ⚫ some new shiny modules for data import in the new shinyHelpers package
• ⚫ the new package recon.ui providing templating for shiny interfaces for RECON packages
• ⚫ a new shiny interface for the incidence package: incidence.ui
• ⚫ a new shiny interface for the epicontacts package: epicontacts.ui
