Update gitpull.js

# Use Named Functions
```javascript
function callback(err, data) {

}
db.get(data, callback); //gives you a stack trace to check with "callback" as a named function
```
instead of...
```javascript
db.get(data, function(){...});
```

# Don't use case statements

# Use module.exports and assume someone wants to consume your library

# Make a command line tool and consume your own API (eat your own dog food!)
