/**
 * Parses any valid JSON text into a POJO model.
 *
 * <h5 class='topic'>Media types</h5>
 * <p>
 * Handles <c>Content-Type</c> types:  <bc>application/json, text/json</bc>
 *
 * <h5 class='topic'>Description</h5>
 * <p>
 * This parser uses a state machine, which makes it very fast and efficient.  It parses JSON in about 70% of the
 * time that it takes the built-in Java DOM parsers to parse equivalent XML.
 *
 * <p>
 * This parser handles all valid JSON syntax.
 * In addition, when strict mode is disable, the parser also handles the following:
 * <ul class='spaced-list'>
 * 	<li>
 * 		Javascript comments (both {@code /*} and {@code //}) are ignored.
 * 	<li>
 * 		Both single and double quoted strings.
 * 	<li>
 * 		Automatically joins concatenated strings (e.g. <code><js>"aaa"</js> + <js>'bbb'</js></code>).
 * 	<li>
 * 		Unquoted attributes and values.
 * </ul>
 *
 * <p>
 * Also handles negative, decimal, hexadecimal, octal, and double numbers, including exponential notation.
 *
 * <p>
 * This parser handles the following input, and automatically returns the corresponding Java class.
 * <ul class='spaced-list'>
 * 	<li>
 * 		JSON objects (<js>"{...}"</js>) are converted to {@link JsonMap JsonMaps}.
 * 		<b>Note:</b>  If a <code><xa>_type</xa>=<xs>'xxx'</xs></code> attribute is specified on the object, then an
 * 		attempt is made to convert the object to an instance of the specified Java bean class.
 * 		See the {@link org.apache.juneau.BeanContext.Builder#typePropertyName(String)} setting for more information about parsing
 * 		beans from JSON.
 * 	<li>
 * 		JSON arrays (<js>"[...]"</js>) are converted to {@link JsonList JsonLists}.
 * 	<li>
 * 		JSON string literals (<js>"'xyz'"</js>) are converted to {@link String Strings}.
 * 	<li>
 * 		JSON numbers (<js>"123"</js>, including octal/hexadecimal/exponential notation) are converted to
 * 		{@link Integer Integers}, {@link Long Longs}, {@link Float Floats}, or {@link Double Doubles} depending on
 * 		whether the number is decimal, and the size of the number.
 * 	<li>
 * 		JSON booleans (<js>"false"</js>) are converted to {@link Boolean Booleans}.
 * 	<li>
 * 		JSON nulls (<js>"null"</js>) are converted to <jk>null</jk>.
 * 	<li>
 * 		Input consisting of only whitespace or JSON comments are converted to <jk>null</jk>.
 * </ul>
 *
 * <p>
 * Input can be any of the following:
 * <ul class='spaced-list'>
 * 	<li>
 * 		<js>"{...}"</js> - Converted to an {@link JsonMap} or an instance of a Java bean if a <xa>_type</xa>
 * 		attribute is present.
 * 	<li>
 * 		<js>"[...]"</js> - Converted to an {@link JsonList}.
 * 	<li>
 * 		<js>"123..."</js> - Converted to a {@link Number} (either {@link Integer}, {@link Long}, {@link Float},
 * 		or {@link Double}).
 * 	<li>
 * 		<js>"true"</js>/<js>"false"</js> - Converted to a {@link Boolean}.
 * 	<li>
 * 		<js>"null"</js> - Returns <jk>null</jk>.
 * 	<li>
 * 		<js>"'xxx'"</js> - Converted to a {@link String}.
 * 	<li>
 * 		<js>"\"xxx\""</js> - Converted to a {@link String}.
 * 	<li>
 * 		<js>"'xxx' + \"yyy\""</js> - Converted to a concatenated {@link String}.
 * </ul>
 *
 * <p>
 * TIP:  If you know you're parsing a JSON object or array, it can be easier to parse it using the
 * {@link JsonMap#JsonMap(CharSequence) JsonMap(CharSequence)} or {@link JsonList#JsonList(CharSequence)
 * JsonList(CharSequence)} constructors instead of using this class.
 * The end result should be the same.
 *
 * <ul class='notes'>
 * 	<li class='note'>This class is thread safe and reusable.
 * </ul>
 *
 * <ul class='seealso'>
 * 	<li class='link'>{@doc jm.JsonDetails}
 * 	<li class='extlink'>{@source}
 * </ul>
