create initial dockerfile

[whitehatmiddleman]

Here is the initial dockerfile for the build. I'm not too familiar with web assembly so I haven't tested the web functionalities yet.

Basically run the following:

# after clone
docker build -t localrun/vial-web .

docker run --rm -it localrun/vial-web /bin/bash

All build files would be under the src/build directory.

Once I figure out running the web assembly part, I'll update it accordingly.
