v0.1.1

• added shell scripts to /mysql/ to start a MySQL server with Docker or Singularity.
• supports soft linking for local-to-local file transfer.
• explicitly show symlinking instead of copying if it makes a symlink.
• for run mode, build singularity image before running a pipeline (local backend only).
  • fix for multiple tasks trying to build on the same image when there is no pre-built image.
