Debugging

**As a** developer
**I need** logging 
**So that** I can debug my code

**Assumptions:** 
* `initialize_logging()` method in `server.py` (similar to professor's code) 
* Log errors
* Boolean variable called `app.debug` that determines if logging occurs

**Acceptance Criteria:**
```
Given that `app.debug = True`
When an error occurs
Then it should be logged 
```
