Title: Added new method to check on which type the connection has

Sometimes you need to distinguish between Wifi and Mobile Connection.

I added the method
```isConnectedToNetworkOfType() -> ReachabilityType```
Which returns an enum value of the type:
```enum ReachabilityType {
case WWAN,
WiFi,
NotConnected
}```

Also enhanced the example for it
