/**
* Loads given method on based on init/watch properties.
* If init is true, method will be executed when view model is initialized.
* If watch is true, method will be executed when any of `this.*.*` properties are
* modified. This method can be asynchronous. Watch will ignore all assignment
* changes within the method.
*
* Every execution will be delayed by parameter specified in {@link ILoadOptions#watchDelayMS},
* so multiple calls can be accumulated and only one final execution will proceed. This is useful
* when you want to load items from API when user is continuously typing in search box.
*
* Method will have an input parameter for cancelToken {@link CancelToken} which you
* can pass it to any REST Api call, before executing next method, cancelToken will
* cancel previous execution.
*
* Either init or watch has to be true, or both can be true as well.
