Rename init-network, remove .getId call (#30)

* Rename init-network, remove .getId call

- Should be called `create-network` to match the existing `create`
  function
- Network#getId oddly has a side effect, which made generative testing
  impossible. Removing this defers network creation until `start!` is called
- Mark init-network as deprecated

* just use def instead of defn

* Fix indentation in README

README.md
