/**

* 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

* coercion for you. The opt methods differ from the get methods in that they do

* not throw. Instead, they return a specified value, such as null.

* <p>

* The <code>put</code> methods add or replace values in 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>.

* <p>

* 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;<small>(comma)</small> may appear just

* before the closing brace.</li>

* <li>Strings may be quoted with <code>'</code>&nbsp;<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>

* </ul>
