/**
 * A JSONObject is an unordered collection of name/value pairs. Its external form is a string wrapped in curly braces
 * with colons between the names and values, and commas between the values and names. The internal form is an object
 * having <code>get</code> and <code>opt</code> methods for accessing the values by name, and <code>put</code> methods
 * for adding or replacing values by name. The values can be any of these types: <code>Boolean</code>,
 * <code>JSONArray</code>, <code>JSONObject</code>, <code>Number</code>, <code>String</code>, or the
 * <code>JSONObject.NULL</code> object. A JSONObject constructor can be used to convert an external form JSON text into
 * an internal form whose values can be retrieved with the <code>get</code> and <code>opt</code> methods, or to convert
 * values into a JSON text using the <code>put</code> and <code>toString</code> methods. A <code>get</code> method
 * returns a value if one can be found, and throws an exception if one cannot be found. An <code>opt</code> method
 * returns a default value instead of throwing an exception, and so is useful for obtaining optional values.
 * 
 * The generic <code>get()</code> and <code>opt()</code> methods return an object, which you can cast or query for type.
 * There are also typed <code>get</code> and <code>opt</code> methods that do type checking and type coercion for you.
 * 
 * The <code>put</code> methods adds values to an object. For example,
 * 
 * <pre>
 * myString = new JSONObject().put(&quot;JSON&quot;, &quot;Hello, World!&quot;).toString();
 * </pre>
 * 
 * produces the string <code>{"JSON": "Hello, World"}</code>.
 * 
 * The texts produced by the <code>toString</code> methods strictly conform to the JSON syntax rules. The constructors
 * are more forgiving in the texts they will accept:
 * <ul>
 * <li>An extra <code>,</code>&nbsp;(comma) may appear just before the closing brace.</li>
 * <li>Strings may be quoted with <code>'</code>&nbsp;(single quote).</li>
 * <li>Strings do not need to be quoted at all if they do not begin with a quote or single quote, and if they do not
 * contain leading or trailing spaces, and if they do not contain any of these characters:
 * <code>{ } [ ] / \ : , = ; #</code> and if they do not look like numbers and if they are not the reserved words
 * <code>true</code>, <code>false</code>, or <code>null</code>.</li>
 * <li>Keys can be followed by <code>=</code> or <code>=></code> as well as by <code>:</code>.</li>
 * <li>Values can be followed by <code>;</code> (semicolon) as well as by <code>,</code>
 * (comma).</li>
 * <li>Numbers may have the <code>0-</code> (octal) or <code>0x-</code> (hex) prefix.</li>
 * </ul>

 * A JSONArray is an ordered sequence of values. Its external text form is a string wrapped in square brackets with

 * these types: <code>Boolean</code>, <code>JSONArray</code>, <code>JSONObject</code>, <code>Number</code>,
 * <code>String</code>, or the <code>JSONObject.NULL object</code>.
 * 
 * The constructor can convert a JSON text into a Java object. The <code>toString</code> method converts to JSON text.
 * 
 * A <code>get</code> method returns a value if one can be found, and throws an exception if one cannot be found. An
 * <code>opt</code> method returns a default value instead of throwing an exception, and so is useful for obtaining
 * optional values.
 * 
 * The generic <code>get()</code> and <code>opt()</code> methods return an object which you can cast or query for type.
 * There are also typed <code>get</code> and <code>opt</code> methods that do type checking and type coercion for you.
 * 
 * The texts produced by the <code>toString</code> methods strictly conform to JSON syntax rules. The constructors are
 * more forgiving in the texts they will accept:
 * <ul>
 * <li>An extra <code>,</code>&nbsp;(comma) may appear just before the closing bracket.</li>
 * <li>The <code>null</code> value will be inserted when there is <code>,</code>&nbsp;(comma) elision.</li>
 * <li>Strings may be quoted with <code>'</code>&nbsp;(single quote).</li>
 * <li>Strings do not need to be quoted at all if they do not begin with a quote or single quote, and if they do not
 * contain leading or trailing spaces, and if they do not contain any of these characters:
 * <code>{ } [ ] / \ : , = ; #</code> and if they do not look like numbers and if they are not the reserved words
 * <code>true</code>, <code>false</code>, or <code>null</code>.</li>
 * <li>Values can be separated by <code>;</code> (semicolon) as well as by <code>,</code>
 * (comma).</li>
 * <li>Numbers may have the <code>0x-</code> (hex) prefix.</li>
