Ngx CountUp Versions Save

• Make the animate method public (thanks @obumnwabude !)
• Support scroll spy
• Fix #47

• Reverted importing from UMD, uses default exported ES6 module
• in 7.3.2 (untagged), made countUp directive import from UMD packaged countUp
• make peer deps more tolerant - effectively adding support for angular 9, 10 (tested)
• changed package name to "ngx-countup" from "countUp.js-angular2"
• added export for countUp directive, thanks @samuel-p #21

• Universal support thanks to @lehoffma
• update peer dependencies to include ng 7 and 8

Improve performance by running CountUp outside the zone. Thanks to @starofall !

• Enable subsequent counting (by updating the end val) to count from the last value (thanks @BorisZubchenko)
• Fix bad condition check in ngOnChanges (thanks @emn178)

• added complete output event
• added ability to defer animation by allowing endVal to be null until you set it

Fixed a bug where the animation smoothing for values greater than 999 resulted in an incorrect end value

Rewritten as Angular app. Published package reflects dist folder. Version updated to 6 to indicate compatibility with Angular 6. Fixed bug where counting down could count up where difference > 999.

Re-packaged with ng-packagr, working in Angular 4
