angular grid demo

[crh225]

Describe the bug

https://stackblitz.com/github/jqwidgets/angular_demos/tree/master/grid/defaultfunctionality?file=src%2Fapp%2Fapp.module.ts

To Reproduce
Steps to reproduce the behavior:
The demo provided on jqwidget site is using any everywhere versus strongly typing objects. It is complaining also about the import path and lint rules not being valid. I have never seen an import statement that imports from a .ts file in angular.

Expected behavior
strongly type the objects and not use any.
fix the import.
