Add a webpage interface for interacting with Autofocus

[Manusreekumar]

As per my understanding, the current interface provides a list of animals along with probability scores, which would be bit difficult for an end user to consume. A simple webpage for uploading the images and getting the predicted tags based on probability cut off seems like a good add on to the package.

Right now I believe our main user is comfortable with consuming JSON dictionaries of probability scores, but I'm open to adding a web interface for other potential users.

Also, does the package currently provide the users with a provision to download the Json output to a file at this point ? Or do they have to use any external sources for doing that?

[gsganden]

Nothing is provided for writing to a file. I think that's fine -- whatever tool a user is using to hit the endpoint (e.g. bash, Python, R) will have its own file-writing capabilities. We can stick with the Linux philosophy of providing a tool that does one thing well and can be piped into other tools.
