D001 - Create local file server

[Donnie]

The app create an Express server to serve files. On encryption of a file, the file name is shown on the app, on clicking the file name one gets the local area network link to the same file, and can share it with colleagues. Who can download the encrypted file and use the same app to decrypt it.

Future plans:

1. Receiver need not use Bitcrypt to decrypt, they can simply use the webserver to download a decrypted version of the file on providing password.
2. Better file handling and management within the app.
