Introduce RW transactions - #139

An empty commit will return early with a all-zero hash and not modify the commit graph. In the future we might want to introduce an option of something like --allow-empty.
Make txn able to read things from table. For now these are mostly dup code from the StoreHandle. I want to redesign the RW interface from coln-store so that might change. For now, we can read stuff inside a transaction.
Closed
Add read/write transactions to coln-store, with typestate. Add convenience methods to do single-shot read/write on the store, internally they will start/finish a transaction for you.

Understood, thanks very much. One thing about the Automerge itself offers similar ways to update documents, so I am not suggesting this isn't useful. Only that I don't think it will be immediately relevant to the work I am doing here. |

Makes sense, feel free to not use it if you think it's not useful in your case :) |

Continuation of #138.
@acurrieclark, I added a couple more stuff so now can do R/W on a transaction, and there are also convenience methods like store.add() which will start a transaction for you, add the value, and immediately close it. In general it is not a good thing to do lots of single-shot commit will consume lots of space, but may be nice to have for demo and experimenting.
See the store-access.test for example
