> Currently the options are to start or not start a kernel at startup time. The "not start" option leaves it all to the user.
> I propose that when the kernel is managing the spark context, that is starts it lazily when the user first tries to get a hold of the reference.
> I tried to do this as part of https://github.com/apache/incubator-toree/pull/15 but hit some roadblocks that I did not want to tackle as part of that PR.
> Now that the `sc`is a `def` it can easily be made lazy.
