Slight wording change?

I wanted to get some opinions on this before going ahead and doing a PR. I got some help proofreading my version of the guide for my upcoming class, and I got a suggestion on 02_getting_started.

In the "Snapshots, not Deltas section", snapshots of repos are defined as being commits. The reader thought it would provide more clarity to reword

When you create a new branch in Git, you are actually just creating a pointer that corresponds to the most recent snapshot in a line of work. Git keeps the snapshots for each branch separate until you explicitly tell it to merge those snapshots into the main line of work.

in the "Branches are Lightweight and Cheap" section. Let me know what you think. I'll make the edits and submit a PR if folks think this is a good modification. Otherwise, feel free to close out this issue.

Hi @amyschoen! I think this looks great. I would love to see this in a PR if you have the bandwidth. 😄 cc @githubtraining/trainers

Cool. I'll get the PR in and make the same changes to my version of the guide as well.
