Docker image is useless except with the CWL example

[ernstki]

If we expect anyone to be able to do anything useful with the Docker image, the README needs to go into enough detail about bind-mounting the input and output directories, so that people can run it on their own data, and write the output to a directory outside the docker image.

Beyond that, the Docker image is only useful for running the one example from the CWL YAML input file, because CWL handles the bind mounts transparently to the user.

The mounting would look like something below along with 10G memory requirement. The bash works fine in windows but having problem in Macs. The actual command can be directly passed to the container (replacing bash) for the analysis.

docker run -m 10G --memory-swap 10G -it -v HOST_DATA_FOLDER:/data -v HOST_OUTPUT_FOLDER:/output weirauchlab/reli bash
