Introducing a directory structure to make it a bit less daunting for new developers and perhaps even old hands. The main folders all start with an upper character, so src files are now located in; * Core - Core data structures * Gui - Main GUI elements * Metrics - Models and Metrics * FileIO - Device and File I/O * Charts - All the chart types * Cloud - Working with Web Resources * Train - Anything Train View specific * ANT - Our ANT+ Stack * Resources - Images, Translations, Web etc Apologies to anyone who needs to merge across this update.
