/**
* <p>
* Assists in implementing {@link Object#hashCode()} methods.
* </p>
* <p/>
* <p>
* This class enables a good <code>hashCode</code> method to be built for any class. It follows the rules laid out in
* the book <a href="http://java.sun.com/docs/books/effective/index.html">Effective Java</a> by Joshua Bloch. Writing a
* good <code>hashCode</code> method is actually quite difficult. This class aims to simplify the process.
* </p>
* <p/>
* <p>
* All relevant fields from the object should be included in the <code>hashCode</code> method. Derived fields may be
* excluded. In general, any field used in the <code>equals</code> method must be used in the <code>hashCode</code>
* method.
* </p>
* <p/>
* <p>
* To use this class write code as follows:
* </p>
* <p/>
* <pre>
* public class Person {
* String name;
* int age;
* boolean smoker;
* ...
*
* public int hashCode() {
* // you pick a hard-coded, randomly chosen, non-zero, odd number
* // ideally different for each class
* return new HashCodeBuilder(17, 37).
* append(name).
* append(age).
* append(smoker).
* toHashCode();
* }
* }
* </pre>
* <p/>
* <p>
* If required, the superclass <code>hashCode()</code> can be added using {@link #appendSuper}.
* </p>
* <p/>
* <p>
* Alternatively, there is a method that uses reflection to determine the fields to test. Because these fields are
* usually private, the method, <code>reflectionHashCode</code>, uses <code>AccessibleObject.setAccessible</code>
* to change the visibility of the fields. This will fail under a security manager, unless the appropriate permissions
* are set up correctly. It is also slower than testing explicitly.
* </p>
* <p/>
* <p>
* A typical invocation for this method would look like:
* </p>
* <p/>
* <pre>
* public int hashCode() {
* return HashCodeBuilder.reflectionHashCode(this);
* }
* </pre>
