Make ImageDescribe a web service

[behroozomidvar]

• Inspired by Google Image Search, design a web service on top of the ImageDescribe engine so that the end-user can simply type in an URL, upload a photo, and receive descriptions immediately.
• Given the fact that the two main objectives of this project is accessibility and availability, an important (but easy) feature for the web service is the text-to-speech feature. There should be a button next to the generated description to read it.
