How to use this package in Angular 4 Application ? #11

Simply const safeJsonStringify = require('safe-json-stringify'); doesn't work in Angular 4. Because we have import statements in Angular 2, 4+ vesrion.
require() is not supported any more. If stringify is exported as class then we can import that class in Angular 4.

Could you tell me "Is it supported for this Angular 4 application ?". If yes, tell me how to use it.

Thanks inadvance!!
