Provision to auto index any new file added to the directory

[kushaldas]

If a new file gets added to the directory, it should be able to auto index that file.

Hey I have tried to bring auto-indexing.

This is the approach I have followed:

Whenever you start the server it basically indexes the files as configured in the RootDirectory.
I used fresh as tools helps me to restart the server when it detects the change in file.

For now the bottle neck it, fresh is not able to recognise nested subdirectories.

This is partially fixed so we will keep it open.

We can use https://github.com/radovskyb/watcher for implementing auto indexing and not depend on fresh for this
