/**
* JSONWriter provides a quick and convenient way of producing JSON text. The

* <p>
* A JSONWriter instance provides a <code>value</code> method for appending
* values to the text, and a <code>key</code> method for adding keys before
* values in objects. There are <code>array</code> and <code>endArray</code>
* methods that make and bound array values, and <code>object</code> and
* <code>endObject</code> methods which make and bound object values. All of
* these methods return the JSONWriter instance, permitting a cascade style. For
* example,
*
* <pre>
* new JSONWriter(myWriter).object().key("JSON").value("Hello, World!").endObject();
* </pre>
*
* which writes
*
* <pre>
* {"JSON":"Hello, World!"}
* </pre>
* <p>
* The first method called must be <code>array</code> or <code>object</code>.
* There are no methods for adding commas or colons. JSONWriter adds them for
* you. Objects and arrays can be nested up to 20 levels deep.
