+/**
+ * A JSONArray is an ordered sequence of values. Its external text form is a
+ * string wrapped in square brackets with commas separating the values. The
+ * internal form is an object having <code>get</code> and <code>opt</code>
+ * methods for accessing the values by index, and <code>put</code> methods for
+ * adding or replacing values. 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 object</code>.
+ * <p>
+ * The constructor can convert a JSON text into a Java object. The
+ * <code>toString</code> method converts to JSON text.
+ * <p>
+ * 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.
+ * <p>
+ * 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;<small>(comma)</small> may appear just
+ *     before the closing bracket.</li>
+ * <li>The <code>null</code> value will be inserted when there
+ *     is <code>,</code>&nbsp;<small>(comma)</small> elision.</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>Values can be separated 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>
+ * </ul>

+/**
+ * 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.
+ * <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 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>
+ * <li>Numbers may have the <code>0-</code> <small>(octal)</small> or
+ *     <code>0x-</code> <small>(hex)</small> prefix.</li>
+ * </ul>

+/**
+ * JSONWriter provides a quick and convenient way of producing JSON text.
+ * The texts produced strictly conform to JSON syntax rules. No whitespace is
+ * added, so the results are ready for transmission or storage. Each instance of
+ * JSONWriter can produce one JSON text.
+ * <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.
+ * <p>
+ * This can sometimes be easier than using a JSONObject to build a string.

+/** A very fast and memory efficient class to encode and decode to and from BASE64 in full accordance
+ * with RFC 2045.<br><br>
+ * On Windows XP sp1 with 1.4.2_04 and later ;), this encoder and decoder is about 10 times faster
+ * on small arrays (10 - 1000 bytes) and 2-3 times as fast on larger arrays (10000 - 1000000 bytes)
+ * compared to <code>sun.misc.Encoder()/Decoder()</code>.<br><br>
+ *
+ * On byte arrays the encoder is about 20% faster than Jakarta Commons Base64 Codec for encode and
+ * about 50% faster for decoding large arrays. This implementation is about twice as fast on very small
+ * arrays (&lt 30 bytes). If source/destination is a <code>String</code> this
+ * version is about three times as fast due to the fact that the Commons Codec result has to be recoded
+ * to a <code>String</code> from <code>byte[]</code>, which is very expensive.<br><br>
+ *
+ * This encode/decode algorithm doesn't create any temporary arrays as many other codecs do, it only
+ * allocates the resulting array. This produces less garbage and it is possible to handle arrays twice
+ * as large as algorithms that create a temporary array. (E.g. Jakarta Commons Codec). It is unknown
+ * whether Sun's <code>sun.misc.Encoder()/Decoder()</code> produce temporary arrays but since performance
+ * is quite low it probably does.<br><br>
+ *
+ * The encoder produces the same output as the Sun one except that the Sun's encoder appends
+ * a trailing line separator if the last character isn't a pad. Unclear why but it only adds to the
+ * length and is probably a side effect. Both are in conformance with RFC 2045 though.<br>
+ * Commons codec seem to always add a trailing line separator.<br><br>
+ *
+ * <b>Note!</b>
+ * The encode/decode method pairs (types) come in three versions with the <b>exact</b> same algorithm and
+ * thus a lot of code redundancy. This is to not create any temporary arrays for transcoding to/from different
+ * format types. The methods not used can simply be commented out.<br><br>
+ *
+ * There is also a "fast" version of all decode methods that works the same way as the normal ones, but
+ * har a few demands on the decoded input. Normally though, these fast verions should be used if the source if
+ * the input is known and it hasn't bee tampered with.<br><br>
