types in package.json thanks to @lavyun

Changed module wrapper to commonjs

Change module wrapper to AMD for best compatibility with both webpack and requirejs

• Rewritten in Typescript
• Jest tests
• Cleaner signature
• Smart easing
• Multiple bundles - with and without rAF polyfill

Fixed a formatting issue where separators were added in front of large negative numbers.

• Refactored formatNumber method to not use RegExp, thanks @mhseiden
• Moved demo js into separate file

Fixed separator check bug (removed separator check)

• Moved modules for Angular 1x and Angular ^2 out of this repo and into their own repos.
• Added support for different numeral systems, so for instance you can use Farsi numerals, thanks @Pourbahrami
• Added error property, so you can check for errors before you call start(). All calls to console.error() removed.

Fixed an issue where calling update in callback would cause infinite rAF.

Fixed an issue where grouping option was ignored.
