Version: 0.0.0
Status: Very early phase. Many of the following info can be obsolete and is subject to change.

1. public methods: ClassName.prototype.publicMethod = function(args) {};
2. protected methods: ClassName.prototype._protectedMethod = function(args) {};
3. private methods: defined as function _privateMethod () {} in Closure.

1. core and main modules don't have to namespace their contributed public methods.

2. 3rd-party moduels and plugins MUST namespace their contributed public methods. plugins are not first-class citizen, in terms that they can only bring in instance methods. 3rd-party module, however, has the full ability as the first-party module. e.g. create sub-namespace under OOPCanvas, and contribute the static class, properties and configurations.

3. module can be defined as a function or an object. if module is defined a function, it will not have submodules. If module has submodules, it needs to be defined as an object, and each of its submodules can be either a function or object.

Architecture
Performance
It seems that hitTest adds quite a lot performace overhead. Add grouping will probably scale down the hitTest process.
Need to re-evaluate if isHitTestVisible should be true by default and its performance implication even when subclass does not override hittest method.
