/**
* Class for Zend_Json encode method.
*
* This class simply holds a string with a native Javascript Expression,
* so objects | arrays to be encoded with Zend_Json can contain native
* Javascript Expressions.
*
* Example:
* <code>
* $foo = array(
* 'integer' =>9,
* 'string' =>'test string',
* 'function' => Zend_Json_Expr(
* 'function(){ window.alert("javascript function encoded by Zend_Json") }'
* ),
* );
*
* Zend_Json::encode($foo, false, array('enableJsonExprFinder' => true));
* // it will returns json encoded string:
* // {"integer":9,"string":"test string","function":function(){window.alert("javascript function encoded by Zend_Json")}}
* </code>
