Add create_user script to insert new users into the database
Fix Docblock Annotation in Bug

Doctrine requires the full '/**' beginning when adding annotations.
Only using a single asterisk, '/*', will not be read correctly, and
thus throw a fatal error.
Update database to account for new entities

```bash
php vendor/bin/doctrine orm:schema-tool:update --force --dump-sql
```

Terminal Result:
> CREATE TABLE bugs (id INTEGER NOT NULL, engineer_id INTEGER DEFAULT NULL, reporter_id INTEGER DEFAULT NULL, description VARCHAR(255) NOT NULL, created DATETIME NOT NULL, status VARCHAR(255) NOT NULL, PRIMARY KEY(id));
> CREATE INDEX IDX_1E197C9F8D8CDF1 ON bugs (engineer_id);

Set default timezone so that Doctrine can handle DateTime correctly

> Fatal error: Uncaught exception 'Exception' with message 'DateTime::__construct(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'America/New_York' for 'EST/-5.0/no DST' instead' in /Users/mode/projects/doctrine-tutorial/create_bug.php:28
