Migrated some old spark-kernel docs to Toree.

Mostly just renames.

Added a section on how to share a the jvm with an external python process.

Great documentation! Please merge this if it is still current

Not sure i have permissions for this repo.

I'm also not quite sure what the live site is. It seems to be the OverhaulSite branch, but should it be?

[mariusvniekerk]

So as far I can tell the live site is pointing to e7ff55? which isn't a tag or anything.

Not entirely sure what is going on with this repo.

We meant to merge in the OverhaulSite branch, but never did. That branch represents the current state of the website.

[mariusvniekerk]

So should we just move master to be at OverhaulSite ?

[chipsenkbeil]

I think so? I feel like something was missing, but overhaul is more up to date.

I guess i missed this one. Looks like most of the renaming and cleanup has been done one way or another, and there are only some new additions that would be great to make to current website. @mariusvniekerk would you be willing to update/merge to master and I would go ahead and publish it after your merge. Or just update this against master and I can handle merge/publish.
