Release 0.2

Background

the release includes the work that I have done for pjs tickets #213 and #422. #422 was originally belong to #213, but first, Anna suggested me to seprate them; Second, there are realy too many differences between the 2D text and 3D text.

Things have done

2D part (#213)

• completed the funtionalities since release 0.1

• fixed a little syntax error
• requested review

3D part (#422)

• implemented the prototype (post)

Challenges

• Using & Managing git.
• WebGL is truly tough. I am still confused how to organize the code of the 3D part
• Javascript. Understaning the sytax, but maybe working more a little bit on that will be much better
• Merging code.
