/**
 * <code>ToString</code> generation routine.
 * <p>
 * This class enables a good toString to be built for any class. This class aims 
 * to simplify the process by:
 * <ul>
 * <li>allowing field names
 * <li>handling all types consistently
 * <li>handling nulls consistently
 * <li>outputting arrays and multi-dimensional arrays
 * <li>enabling the detail level to be controlled for objects and collections
 * </ul>
 * <p>
 * To use this class write code as follows:
 * <pre>
 * public class Person {
 *   String name;
 *   int age;
 *   boolean isSmoker;
 * 
 *   ...
 * 
 *   public String toString() {
 *     return new ToStringBuilder(this).
 *       append(name, "name").
 *       append(age, "age").
 *       append(smoker, "smoker").
 *       toString();
 *   }
 * }
 * </pre>
 * This will produce a toString of the format:
 * <code>Person@7f54[name=Stephen,age=29,smoker=false]</code>
 * <p>
 * Alternatively, there is a method that uses reflection to determine
 * the fields to test. Because these fields are usually private, the method, 
 * <code>reflectionToString</code>, uses <code>Field.setAccessible</code> to change
 * the visibility of the fields. This will fail under a security manager, 
 * unless the appropriate permissions are set. It is also slower than testing 
 * explicitly.
 * <p>
 * A typical invocation for this method would look like:
 * <pre>
 * public String toString() {
 *   return ToStringBuilder.reflectionToString(this);
 * }
 * </pre>
 * <p>
 * The exact format of the toString is determined by the {@link ToStringStyle}
 * passed into the constructor.
