And the example # nvim-oxi/examples/api

1. add testing bash scripts for examples 2. add `src/test.rs` which takes snapshots for: * calc & mechanic: succeeded * mlua & api: failed noib3#54

Wow the mlua example works now 👍 I notice the example directory structure has changed: when So I have to git clone my fork again to test it. Thankfully, nothing goes wrong. |

Just a heads up, I was having issues with the API examples (api.open_window() command), which lead me to this thread. I went to test out the script posted above, and ended up with the same issue _ ✗ ./examples.sh
