/**
 * Bean context.
 *
 * <p>
 * This class servers multiple purposes:
 * <ul class='spaced-list'>
 *    <li>
 *       Provides the ability to wrap beans inside {@link Map} interfaces.
 *    <li>
 *       Serves as a repository for metadata on POJOs, such as associated {@link Bean @Bean} annotations,
 *       {@link PropertyNamer PropertyNamers}, etc...  which are used to tailor how POJOs are serialized and parsed.
 * </ul>
 *
 * <p>
 * All serializers and parsers use this context so that they can handle POJOs using a common framework.
 *
 * <h5 class='topic'>Bean Contexts</h5>
 *
 * <p>
 * Bean contexts are created through the {@link BeanContext#create() BeanContext.create()} and {@link Builder#build()} methods.
 * <br>These context objects are read-only, reusable, and thread-safe.
 *
 * <p>
 * Each bean context maintains a cache of {@link ClassMeta} objects that describe information about classes encountered.
 * These <c>ClassMeta</c> objects are time-consuming to construct.
 * Therefore, instances of {@link BeanContext} that share the same <js>"BeanContext.*"</js> property values share
 * the same cache.  This allows for efficient reuse of <c>ClassMeta</c> objects so that the information about
 * classes only needs to be calculated once.
 * Because of this, many of the properties defined on the {@link BeanContext} class cannot be overridden on the session.
 *
 * <h5 class='topic'>Bean Sessions</h5>
 *
 * <p>
 * Whereas <c>BeanContext</c> objects are permanent, unchangeable, cached, and thread-safe,
 * {@link BeanSession} objects are ephemeral and not thread-safe.
 * They are meant to be used as quickly-constructed scratchpads for creating bean maps.
 * {@link BeanMap} objects can only be created through the session.
 *
 * <h5 class='topic'>BeanContext configuration properties</h5>
 *
 * <p>
 * <c>BeanContexts</c> have several configuration properties that can be used to tweak behavior on how beans are
 * handled.  These are denoted as the static <jsf>BEAN_*</jsf> fields on this class.
 *
 * <p>
 * Some settings (e.g. {@link Builder#beansRequireDefaultConstructor()}) are used to differentiate between bean
 * and non-bean classes.
 * Attempting to create a bean map around one of these objects will throw a {@link BeanRuntimeException}.
 * The purpose for this behavior is so that the serializers can identify these non-bean classes and convert them to
 * plain strings using the {@link Object#toString()} method.
 *
 * <p>
 * Some settings (e.g. {@link Builder#beanFieldVisibility(Visibility)}) are used to determine what kinds of properties are
 * detected on beans.
 *
 * <p>
 * Some settings (e.g. {@link Builder#beanMapPutReturnsOldValue()}) change the runtime behavior of bean maps.
 *
 * <h5 class='section'>Example:</h5>
 *
 * <p class='bjava'>
 *    <jc>// Construct a context from scratch.</jc>
 *    BeanContext <jv>beanContext</jv> = BeanContext
 *       .<jsm>create</jsm>()
 *       .beansRequireDefaultConstructor()
 *       .notBeanClasses(Foo.<jk>class</jk>)
 *       .build();
 * </p>
 *
 * <h5 class='topic'>Bean Maps</h5>
 *
 * <p>
 * {@link BeanMap BeanMaps} are wrappers around Java beans that allow properties to be retrieved and
 * set using the common {@link Map#put(Object,Object)} and {@link Map#get(Object)} methods.
 *
 * <p>
 * Bean maps are created in two ways...
 * <ol>
 *    <li>{@link BeanSession#toBeanMap(Object) BeanSession.toBeanMap()} - Wraps an existing bean inside a {@code Map}
 *       wrapper.
 *    <li>{@link BeanSession#newBeanMap(Class) BeanSession.newBeanMap()} - Create a new bean instance wrapped in a
 *       {@code Map} wrapper.
 * </ol>
 *
 * <h5 class='section'>Example:</h5>
 *
 * <p class='bjava'>
 *    <jc>// A sample bean class</jc>
 *    <jk>public class</jk> Person {
 *       <jk>public</jk> String getName();
 *       <jk>public void</jk> setName(String <jv>name</jv>);
 *       <jk>public int</jk> getAge();
 *       <jk>public void</jk> setAge(<jk>int</jk> <jv>age</jv>);
 *    }
 *
 *    <jc>// Create a new bean session</jc>
 *    BeanSession <jv>session</jv> = BeanContext.<jsf>DEFAULT</jsf>.createSession();
 *
 *    <jc>// Wrap an existing bean in a new bean map</jc>
 *    BeanMap&lt;Person&gt; <jv>map1</jv> = <jv>session</jv>.toBeanMap(<jk>new</jk> Person());
 *    <jv>map1</jv>.put(<js>"name"</js>, <js>"John Smith"</js>);
 *    <jv>map1</jv>.put(<js>"age"</js>, 45);
 *
 *    <jc>// Create a new bean instance wrapped in a new bean map</jc>
 *    BeanMap&lt;Person&gt; <jv>map2</jv> = <jv>session</jv>.newBeanMap(Person.<jk>class</jk>);
 *    <jv>map2</jv>.put(<js>"name"</js>, <js>"John Smith"</js>);
 *    <jv>map2</jv>.put(<js>"age"</js>, 45);
 *    Person <jv>person</jv> = <jv>map2</jv>.getBean();  <jc>// Get the bean instance that was created.</jc>
