Add brief tutorial on how to create custom base box

[philred]

I know that this build is based on HEAD builds, but I think it would be helpful to have a basic tutorial on how to add a custom base box to atlas in the README so that we can utilize this process for installations that aren't on HEAD.

@philred can you clarify what you mean by HEAD? Do you mean Islandora Foundation modules and libraries? If so, that'd be an issue for islandora_vagrant since the base box doesn't pull those in.

[philred]

@ruebot I sure can! I think the best explanation would be an example. We've been customizing the old islandora_vagrant as a development copy of our existing islandora, which is not running on HEAD. So we've had to customize not just the islandora repos, but also fedora/solr/gsearch etc versions to match as closely as we can our existing environment.

We have the vagrant code for our custom install, but I wasn't sure exactly how you are creating and deploying the atlas base box.

Ah, ok. Process basically goes like this:

1. clone this repo
2. vagrant up
3. vagrant package --base whatever_you_want_to_name_it
4. Upload to atlas

So, that said, if you want to outline the process in the README, feel free too. Pull requests are always welcome 😄

[philred]

Great, we'll work on that and see what we come up with.
