/**
|

|
|
* Example of Character instantiation using Property pattern (as concept also known like Prototype inheritance).
|
||
|
|
* In prototype inheritance instead of classes, as opposite to Java class inheritance,
|
||
|
|
* objects are used to create another objects and object hierarchies.
|
||
|
|
* Hierarchies are created using prototype chain through delegation: every object has link to parent object.
|
||
|
|
* Any base (parent) object can be amended at runtime (by adding or removal of some property), and all child objects will be affected as result.
