Not sure why we have iterating parameters is required. Base on API (http://developer.github.com/v3/orgs/#list-user-organizations), there are no parameters for  List Organizations API
```
/**
     * Iterate them all.
     * @param params Iterating parameters, as requested by API
     * @return Iterator of Organizations
     * @see <a href="http://developer.github.com/v3/orgs/#list-user-organizations">List Organizations</a>
     */
    @NotNull(message = "iterable is never NULL")
    Iterable<Organization> iterate(
        @NotNull(message = "map of params can't be NULL")
        Map<String, String> params);
```
