/**
* 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>

* Kim makes immutable eight bit Unicode strings. If the MSB of a byte is set,
* then the next byte is a continuation byte. The last byte of a character
* never has the MSB reset. Every byte that is not the last byte has the MSB
* set. Kim stands for "Keep it minimal". A Unicode character is never longer
* than 3 bytes. Every byte contributes 7 bits to the character. ASCII is
* unmodified.
*
* Kim UTF-8
* one byte U+007F U+007F
* two bytes U+3FFF U+07FF
* three bytes U+10FFF U+FFFF
* four bytes U+10FFFF
*
* Characters in the ranges U+0800..U+3FFF and U+10000..U+10FFFF will be one
* byte smaller when encoded in Kim compared to UTF-8.
*
* Kim is beneficial when using scripts such as Old South Arabian, Aramaic,
* Avestan, Balinese, Batak, Bopomofo, Buginese, Buhid, Carian, Cherokee,
* Coptic, Cyrillic, Deseret, Egyptian Hieroglyphs, Ethiopic, Georgian,
* Glagolitic, Gothic, Hangul Jamo, Hanunoo, Hiragana, Kanbun, Kaithi,

* Phoenician, Samaritan, Sharada, Sinhala, Sora Sompeng, Tagalog, Tagbanwa,
* Takri, Tai Le, Tai Tham, Tamil, Telugu, Thai, Tibetan, Tifinagh, UCAS.
*
* A kim object can be constructed from an ordinary UTF-16 string, or from a
* byte array. A kim object can produce a UTF-16 string.
*
* As with UTF-8, it is possible to detect character boundaries within a byte

/**
* JSONzip is a binary-encoded JSON dialect. It is designed to compress the
* messages in a session. It is adaptive, so with each message seen, it should
* improve its compression. It minimizes JSON's overhead, reducing punctuation
* to a small number of bits. It uses Huffman encoding to reduce the average
* size of characters. It uses caches (or Keeps) to keep recently seen strings
* and values, so repetitive content (such as object keys) can be
* substantially reduced. It uses a character encoding called Kim (Keep it
* minimal) that is smaller than UTF-8 for most East European, African, and
* Asian scripts.
*
* JSONzip tends to reduce most content by about half. If there is a lot of
* recurring information, the reduction can be much more dramatic.
*
* FOR EVALUATION PURPOSES ONLY. THIS PACKAGE HAS NOT YET BEEN TESTED
* ADEQUATELY FOR PRODUCTION USE.
