* [TD]allow DrawViewAnno to be attached to another view * [TD]allow image and spreadsheet attach to view * [TD]ensure correct parent in scene * [TD]refactor command helpers to separate file - gathering the helpers in one place - helper redundancy to be address in another change * [TD]create symbol, spreadsheet, image with parent * [TD]fix claimChildren for some views - also includes many lint fixes
