Added a tutorial for bundle adjustment in isis

[AustinSanders]

Adds a bundle adjustment tutorial. Should probably be fact checked, since I'm definitely not an expert in the art of bundle adjustment.

Closes #11 and Closes #51

I'm struggling to integrate that information into a 'how-to-guide' -- a lot of it falls into application documentation and concepts. Would it be acceptable to make a bundle adjustment concept doc that includes that info instead?

Honestly this may be better on the actual jigsaw app docs page.

This reads more like a high level, general about than a tutorial. If that is the intention 👍. If not, I believe this needs to have a small amount of actual data with described inputs and outputs that one can copy/paste to run.

Then is needs a discussion of the outputs. Right now, someone is going to get a wall of text/numbers and have no idea what they are looking at.

As somewhat of a newbie, I was able to go through the tutorial and get the same result at the end. (I only have a basic understanding of the whole bundle-adjustment process, may read more into jigsaw docs later as suggested at the top.) The data added made it much easier to follow along.
