==================[ Server protocol ]==================

The server now offers one additional API:

1. Tracking a cat:

GET
track.pl?name=<username>&password=<password>&catid=<id>&lat=<latutide>&lng=<longitude>

E.g.: track.pl?name=sergey&password=1234&catid=1&lat=74.2523&lng=74.2134

Returns the distance and the bearing to the current position of the tracked cat
from your submitted location:

{status: "OK", "distance":25.301498, "bearing":223.29565, "catId":"1"}

or an error: 

{ "status":"ERROR", "code": "MISSING_ID",  "reason": "Cat ID missing from request" }
{ "status":"ERROR", "code": "NO_ID",       "reason": "No cat by that ID" }
{ "status":"ERROR", "code": "MISSING_LAT", "reason": "Latitude missing from request" }
{ "status":"ERROR", "code": "MISSING_LNG", "reason": "Longitude missing from request" }

The error codes are fixed. The code field in a response is expected to precisely match one
these fixed values.

In the hard mode, the cats move around every 2 minutes. 

NOTE: To get the cats moving, you need to reactivate the hard mode by 
      resetting your catlist. If you don't reset your list, your cats
      will not move.
