Implement a html page for front-end UI

[liqingyang1606]

This issue is related to bullet 1 of Requirement 4: create a simple single page UI for your application.

• make a directory ./services/static/
• index.html, which is the single page UI for our application
• ./services/static/css/, which contains CSS files to define the layout of the webpage
• ./services/static/images/, which contains images used in the webpage (only an icon)
• ./services/static/js/, which contains JavaScript files to define the logic of the webpage. You should write other stories to develop and test the front-end functions using BDD
