Arrows Config Support (#6)

* WIP Simplification update to use arrows only for generator assignment & config

* Mappings tabbed replaced with auto generated mappings from specially formatted arrows.app json files

* Generator search and code copy in design tab added

* Config tab removed

* Import, Generate, and Export tabs combined into new Generate tab

* Design tab updated with new instructions

* Clean up and instructions added
