/**
 * Class that builds {@link InitialConfigPrimitiveBuilder} instances. Overall design of the class is that of a
 * <a href="https://en.wikipedia.org/wiki/Fluent_interface">fluent interface</a>, where method chaining is used.
 * 
 * <p>
 * In general, this class is supposed to be used like this template:
 * <pre>
 *   <code>
 *     InitialConfigPrimitiveBuilder createTarget(int fooXyzzy, int barBaz) {
 *         return new InitialConfigPrimitiveBuilderBuilder()
 *             .setFoo(new FooBuilder().setXyzzy(fooXyzzy).build())
 *             .setBar(new BarBuilder().setBaz(barBaz).build())
 *             .build();
 *     }
 *   </code>
 * </pre>
 * 
 * <p>
 * This pattern is supported by the immutable nature of InitialConfigPrimitiveBuilder, as instances can be freely passed around without
 * worrying about synchronization issues.
 * 
 * <p>
 * As a side note: method chaining results in:
 * <ul>
 *   <li>very efficient Java bytecode, as the method invocation result, in this case the Builder reference, is
 *       on the stack, so further method invocations just need to fill method arguments for the next method
 *       invocation, which is terminated by {@link #build()}, which is then returned from the method</li>
 *   <li>better understanding by humans, as the scope of mutable state (the builder) is kept to a minimum and is
 *       very localized</li>
 *   <li>better optimization oportunities, as the object scope is minimized in terms of invocation (rather than
 *       method) stack, making <a href="https://en.wikipedia.org/wiki/Escape_analysis">escape analysis</a> a lot
 *       easier. Given enough compiler (JIT/AOT) prowess, the cost of th builder object can be completely
 *       eliminated</li>
 * </ul>
