This method is called in the last line of a Wijmo component constructor and allows you to not declare your custom component's constructor at all, thus preventing you from a necessity to maintain constructor parameters and keep them in synch with Wijmo component's constructor parameters.
Returns void

name: string
The annotation's name.
Returns AnnotationBase
