./windc/core/builders folder. The class name should be the same as module file name. 2. Updated core/api.py to support datacenter and service creation with extra parameters which are not defined by model explicitly. 3. Added event based approach for the windows environment change. Now when user submits a request to API the core updates database and initiates a new event which defined scope (datacenter, service, VM) and action (add, modify, delete). This event and data will be iterated over all registered builders. Each builder can use this event and data to plan some modification.
