    Rules to build the ONOS GUI 2
    The GUI2 Angular 7 elements are built here with Angular CLI 'ng'
    Some work is being done in the Bazel community to integrate Bazel and
    Angular 7, (Angular Buildtools Convergence -
    https://docs.google.com/document/d/1OlyiUnoTirUj4gecGxJeZBcjHcFr36RvLsvpBl2mxA8/preview)
    but it is in the very early stages (Aug'18) and not yet fit
    for production and at present it works as a replacement for Angular CLI
    (which is not desirable).
    There are plans to extend Bazel it to work with Angular CLI, and if works
    well this Bazel file may be rearchiteced in future.
    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.
