Hi guys,

Here is my proposal for this code challenge.

Pros:
- it automates the logs. You don't have to remember to insert log every time you save a Task (creation, update, reception on answer from provider) 
- reduces code duplication and maintenance.

Cons:
- I think it's preferable that models only take care of saving their own data.
- In some cases, you might not want to add entry in logs
