* Removed sort by memberof, when the memberOf is the same of items then sort function doesn't works correctly.
Added Unit Tests
Fixed#838
* Flow.js : added flow notation for sort.js
* build: Use Flow syntax without comments.
We're switching to Flow annotations - not Flow comments. This
gives documentation.js the ability to self-document without
JSDoc types and improves our compatibility with tools like
prettier.
Fixes#729. Fixes#709
