Generate a list of SID -> Service names
Hi, 

I found it very hard to apply human readable sensors names as for each sensor you have to: 
- know the sid
- know the type
- look up in code the services associated with the type. 
- edit it in defaultValues

I tried to implement a function to print out the sid to name mapping like 

          "12356583246928359": {
                    "ContactSensor_ContactSensor": {
                               "name": "ContactSensor_1234"
                   }"
            }

so I just have to change the values in the JSON for *name* 
However it looks Accessories and Devices are not associated at all?
Is there any code to look up an Accessory by sid + gatewayId? 


_UPDATE_:

I found that in index.js, line 253 should read:
          
           that.DeviceUtil.update(gatewaySid, {model: result['model']});

and line 287: 
  
           that.DeviceUtil.update(deviceSid, {model: result['model']});

Then the device list contains also model information so it is possible to traverse the code.
