+/**
+ * The builder annotation creates a so-called 'builder' aspect to the class that is annotated or the class
+ * that contains a member which is annotated with {@code @Builder}.
+ * <p>
+ * If a member is annotated, it must be either a constructor or a static method. If a class is annotated,
+ * then a private constructor is generated with all fields as arguments
+ * (as if {@code @AllArgsConstructor(AccessLevel.PRIVATE)} is present
+ * on the class), and it is as if this constructor has been annotated with {@code @Builder} instead.
+ * <p>
+ * The effect of {@code @Builder} is that an inner class is generated named <code><strong>T</strong>Builder</code>,
+ * with a private constructor. Instances of <code><strong>T</strong>Builder</code> are made with the static
+ * method named {@code builder()} which is also generated for you in the class itself (not in the builder class).
+ * <p>
+ * The <code><strong>T</strong>Builder</code> class contains 1 method for each parameter of the annotated
+ * constructor / static method (each field, when annotating a class), which returns the builder itself.
+ * The builder also has a <code>build()</code> method which returns a completed instance of the original type,
+ * created by passing all parameters as set via the various other methods in the builder to the constructor
+ * or static method that was annotated with {@code @Builder}. The return type of this method will be the same
+ * as the relevant class, unless a static method has been annotated, in which case it'll be equal to the
+ * return type of that method.
+ * <p>
+ * Complete documentation is found at <a href="http://projectlombok.org/features/experimental/Builder.html">the project lombok features page for &#64;Builder</a>.
