v0.3.0

[masayuki0812]

Introduce new architecture that enables more flexible extension.

• Basically same interface with v0.2.x
• Introduce prototype architecture to allow us to define custom API and change the default behavior.
• Introduce a concept of internal to keep simplicity of chart object and distinguish API (external) and internal functions and variables
• Split c3.js into small src files in order to improve modularity
• Introduce unit test

An example of the code base:

// same interface with the current version
var chart = c3.generate({ ... });
chart.focus(...);

// introduce internal API so that we can access internal variables and functions
chart.internal;
chart.internal.isTimeseries(); // isTimeseries is an internal function, but now we can access

// you can define custom API through c3.chart.fn
c3.chart.fn.myApi = function(){
   // isTimeseries is an internal variable, but now we can access in API definition
   this.internal.isTimeseries(); 
};
chart.myApi() // now we can call this

// you can change the behavior of internal functions through c3.chart.internal.fn
c3.chart.internal.fn.drawLine = function() {
   if (this.isTimeseries()) {
     // do something
   } else {
     // do something
   }
};

Hi @masayuki0812, thank you for jour job, I use your library and is awesome, everything is too easy to use. Now my question ;).
I try to use a gauge chart, and I need to put a custom legend, to explain the thresholds used to draw it. Do you have some tutorial about extends the functionality or where I can review to learn it?. Thank you
