/**
* 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.
* <p>
* 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
* coersion for you.
* <p>
* The <code>put</code> methods adds values to an object. For example, <pre>
* myString = new JSONObject().put("JSON", "Hello, World!").toString();</pre>
* produces the string <code>{"JSON": "Hello, World"}</code>.
* <p>
* The texts produced by the <code>toString</code> methods strictly conform to
* the JSON sysntax rules.
* The constructors are more forgiving in the texts they will accept:
* <ul>
* <li>An extra <code>,</code> <small>(comma)</small> may appear just
* before the closing brace.</li>
* <li>Strings may be quoted with <code>'</code> <small>(single
* quote)</small>.</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> <small>(semicolon)</small> as
* well as by <code>,</code> <small>(comma)</small>.</li>
* <li>Numbers may have the <code>0-</code> <small>(octal)</small> or
* <code>0x-</code> <small>(hex)</small> prefix.</li>
* <li>Comments written in the slashshlash, slashstar, and hash conventions
* will be ignored.</li>
* </ul>
