Add snippets to repo

This currently is a start of the snippets. This PR is not ready but more to see if this matches what we had in mind for structure. This request comes from #32 and if I hear this is the right direction, I'll continue the transfer.

Current structure is code has been tabbed in to be distinguished. It would be better in markdown or ReSt IMO but I understand a want for simplicity like the `.txt` files in the member folder.
