Changes in function of docker deployment

[gadeynebram]

@ceefluz ,

I've created a Docker image to run RadaR. Are you familiar with Docker?

Would these changes be oké to make RadaR more docker compatible?

• I've moved the data files to a separate data directory so that this directory can be mounted and the data replaced with the user's dataset.
• I've renamed the sample files so that the date suffix if removed.
• I've moved the code that installs dependencies to a separate file dependencies.R. This way they can be installed when docker builds the image and this does not have to happen each time the container is run.

Haven't worked with docker yet, but happy about your changes!
