   * 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.
