Some notes:

1. The docker container must be run with the --privileged flag for lldb to work.
2. After starting, neovim is run and installs vim-vebugger automatically. When finished, neovim should be reopened.
3. A small test program with a segmentation fault in stored in ~. Start vim-vebugger with:

   VBGstartLLDB ./test
   VBGcontinue
