1. Migrate Code Base to TypeScript

We migrated our codebase to TypeScript. It's not an easy job, but we are glad we've made this tough decision at the beginning. And now we benefit a lot from it when refacting codes to add new features.

2. Animation Improvement for Storytelling

I can't successfully build next branch and throw Could not resolve zrender.

[plainheart]

@susiwen8 zrender also should be switched to next branch and a soft link from local zrender to node_modules/zrender is needed.
Mac OS may refer to Wiki: How-to-setup-the-dev-environment
Windows may also refer to Wiki: How-to-setup-the-dev-environment, but it needs to pay extra attention to how to create a soft link in Windows.

[susiwen8]

@plainheart Thanks, maybe this should be added

[pissang]

@susiwen8 Added how to link zrender. Sorry for missing it.

[plainheart]

Added how to create a soft link to zrender for those developers who are using Windows CMD.

[Ovilia]

@plainheart Thanks. Where did you make the changes? I didn't see that in wiki history.

Where did you make the changes? I didn't see that in wiki history.

Just added it into How to run the branch area for this issue. Is it needed to add to Wiki?

[plainheart]

@Ovilia Done. I think it might be a little beneficial to developers who are using Windows.

[Ovilia]

@plainheart Thanks!
