Static ui

All responsive and almost ready to go! Index.html and About.html just need to be copied over into corresponding .html files in templates/ folder (then delete original index.html and about.html files?) cc/ @lyzidiamond 

*You may want to test UI while running the full app with real data e.g. I can't view what Index.html looks like you enter an address and the json displays below the input field. Or what it looks like when you upload a file. LMK if additional changes are needed there.

Opened PR to merge with lex-deploy, is this the correct branch? Go team <3
