Todos of v0.0.4 - Deps upgrade and demo codes rearrangement

[hijiangtao]

Thanks for your support on glmaps project, there's not too much improvements since last few months ago, but with technologies moving forward, the repo itself should be reviewed again so as to get the pace of its' deps (three.js and deck.gl).

Previous release and future todos

I just release v0.0.3 of glmaps, and it will be the last version which still supports deck.gl @v6.4.x. In the next version, I should focus on following things:

1. Upgrade deps such as deck.gl to v7, so that to allow developers use glmaps with deps' new grammar (in map visualization aspect);
   • deck.gl @v7
   • three.js codes review
   • react-map-gl codes review
   • mapbox codes review
2. Rearrange the demo codes, to make current data visualization example codes clear with later added WebGL example codes, as well as building a bundle of them to let developers preview the effects online;
   • glmaps demo codes (layers)
   • glmaps demo codes (globe)
   • WebGL demo codes
   • Bundle and preview deployment
3. Other improvements such as visualization tools for people who don't know how to code, etc.
   • Map Data visualization tools (Plan to support input data format with CSV, JSON, TSV, etc)

Besides, the tutorials will be suspended since I don't have enough time in putting my thoughts from codes to articles.

Developing arrangement

I add a new project in tracking the progress of v0.0.4, and I also add a CHANGELOG of glmaps, you can find previous changes in it with details.

• master branch contains the latest stable data visualization codes and tutorials;
• dev branch is for regular development of glmaps;
• feat-deck-v7 branch is used in developing v0.0.4, and it should contains all the new features mentioned above;

If you have any ideas about glmaps' development, you can comment or open a PR to let me know it. Last, please feel freee to star glmaps if you think it‘s a cool project!
