    Rules to build the ONOS GUI

    Bazel and npm are incompatibe in how they deal with files. npm likes to follow links
    to get back to the original canonical path names, and bazel uses links extensively when
    populating the sandbox. To get around these problems, the rules that follow use filegroups
    to specify the files as dependencies and then use a genrule to convert the files into a tar
    ball. Once the tar ball is unrolled into the sandbox, the links are broken, but the build is
    still hermetic since those files are referred to as dependencies in the genrule.

    Also note that the onos-gui.tar contains files from //tools/gui and //web/gui, so the files are placed into
    the sandbox at the proper locations and then returned as a tar ball.
