/**
 * Serializes POJO models to JSON.
 *
 * <h5 class='topic'>Media types</h5>
 * <p>
 * Handles <c>Accept</c> types:  <bc>application/json, text/json</bc>
 * <p>
 * Produces <c>Content-Type</c> types:  <bc>application/json</bc>
 *
 * <h5 class='topic'>Description</h5>
 * <p>
 * The conversion is as follows...
 * <ul class='spaced-list'>
 * 	<li>
 * 		Maps (e.g. {@link HashMap HashMaps}, {@link TreeMap TreeMaps}) are converted to JSON objects.
 * 	<li>
 * 		Collections (e.g. {@link HashSet HashSets}, {@link LinkedList LinkedLists}) and Java arrays are converted to
 * 		JSON arrays.
 * 	<li>
 * 		{@link String Strings} are converted to JSON strings.
 * 	<li>
 * 		{@link Number Numbers} (e.g. {@link Integer}, {@link Long}, {@link Double}) are converted to JSON numbers.
 * 	<li>
 * 		{@link Boolean Booleans} are converted to JSON booleans.
 * 	<li>
 * 		{@code nulls} are converted to JSON nulls.
 * 	<li>
 * 		{@code arrays} are converted to JSON arrays.
 * 	<li>
 * 		{@code beans} are converted to JSON objects.
 * </ul>
 *
 * <p>
 * The types above are considered "JSON-primitive" object types.
 * Any non-JSON-primitive object types are transformed into JSON-primitive object types through
 * {@link org.apache.juneau.swap.ObjectSwap ObjectSwaps} associated through the
 * {@link org.apache.juneau.BeanContext.Builder#swaps(Class...)} method.
 * Several default transforms are provided for transforming Dates, Enums, Iterators, etc...
 *
 * <p>
 * This serializer provides several serialization options.
 * Typically, one of the predefined DEFAULT serializers will be sufficient.
 * However, custom serializers can be constructed to fine-tune behavior.
 *
 * <h5 class='topic'>Behavior-specific subclasses</h5>
 * <p>
 * The following direct subclasses are provided for convenience:
 * <ul class='spaced-list'>
 * 	<li>
 * 		{@link SimpleJsonSerializer} - Default serializer, single quotes, simple mode.
 * 	<li>
 * 		{@link SimpleJsonSerializer.Readable} - Default serializer, single quotes, simple mode, with whitespace.
 * </ul>
 *
 * <h5 class='section'>Example:</h5>
 * <p class='bjava'>
 * 	<jc>// Use one of the default serializers to serialize a POJO</jc>
 * 	String <jv>json</jv> = JsonSerializer.<jsf>DEFAULT</jsf>.serialize(<jv>someObject</jv>);
 *
 * 	<jc>// Create a custom serializer for lax syntax using single quote characters</jc>
 * 	JsonSerializer <jv>serializer</jv> = JsonSerializer.<jsm>create</jsm>().simple().sq().build();
 *
 * 	<jc>// Clone an existing serializer and modify it to use single-quotes</jc>
 * 	<jv>serializer</jv> = JsonSerializer.<jsf>DEFAULT</jsf>.copy().sq().build();
 *
 * 	<jc>// Serialize a POJO to JSON</jc>
 * 	String <jv>json</jv> = <jv>serializer</jv>.serialize(<jv>someObject</jv>);
 * </p>
 *
 * <ul class='notes'>
 * 	<li class='note'>This class is thread safe and reusable.
 * </ul>

 * <ul class='seealso'>
