/**
*
*
* This is the Builder pattern variation as described by Joshua Bloch in
* Effective Java 2nd Edition.
*
*
* We want to build Hero objects, but its construction is complex because of the
* many parameters needed. To aid the user we introduce HeroBuilder class.
* HeroBuilder takes the minimum parameters to build Hero object in its
* constructor. After that additional configuration for the Hero object can be
* done using the fluent HeroBuilder interface. When configuration is ready the
* build method is called to receive the final Hero object.
