+/**
+ * Converts to and from JSON format.
+ *
+ * JSON (JavaScript Object Notation) is a lightweight data-interchange
+ * format. It is easy for humans to read and write. It is easy for machines
+ * to parse and generate. It is based on a subset of the JavaScript
+ * Programming Language, Standard ECMA-262 3rd Edition - December 1999.
+ * This feature can also be found in  Python. JSON is a text format that is
+ * completely language independent but uses conventions that are familiar
+ * to programmers of the C-family of languages, including C, C++, C#, Java,
+ * JavaScript, Perl, TCL, and many others. These properties make JSON an
+ * ideal data-interchange language.
+ *
+ * This package provides a simple encoder and decoder for JSON notation. It
+ * is intended for use with client-side Javascript applications that make
+ * use of HTTPRequest to perform server communication functions - data can
+ * be encoded into JSON notation for use in a client-side javascript, or
+ * decoded from incoming Javascript requests. JSON format is native to
+ * Javascript, and can be directly eval()'ed with no further parsing
+ * overhead
+ *
+ * All strings should be in ASCII or UTF-8 format!

+	 * Class PDO
+		 * 	PostgreSQL, SQLITE and MYSQL PDO support for PHP 4.X.X or PHP 5.0.X users, compatible with PHP 5.1.0 (RC1).
+		 *
+		 * DESCRIPTION [directly from http://us2.php.net/manual/en/ref.pdo.php]
+	 * 	The PHP Data Objects (PDO) extension defines a lightweight, consistent interface for accessing databases in PHP.
+		 *	  Each database driver that implements the PDO interface can expose database-specific features as regular extension functions.
+		 *	  Note that you cannot perform any database functions using the PDO extension by itself;
+		 *	  you must use a database-specific PDO driver to access a database server.
+		 *
+		 * HOW TO USE
+		 * 	To know how to use PDO driver and all its methods visit php.net wonderful documentation.
+		 *	  http://us2.php.net/manual/en/ref.pdo.php
+		 *	  In this class some methods are not available and actually this porting is only for MySQL, SQLITE and PostgreSQL.
+		 *
+		 * LIMITS
+		 * 	For some reasons ( time and php used version with this class ) some PDO methods are not availables and
+		 *	  someother are not totally supported.
+		 *
+		 *	  PDO :: UNSUPPORTED METHODS:
+		 *	  	- beginTransaction 	[ mysql 3 has not transaction and manage them is possible only with a direct BEGIN
+		 *			  			  or COMMIT query ]
+		 *			  - commit
+		 *			  - rollback
+		 *
+		 *	  PDO :: NOT TOTALLY SUPPORTED METHODS:
+		 *	  	- getAttribute		[ accepts only PDO_ATTR_SERVER_INFO, PDO_ATTR_SERVER_VERSION,
+		 *			  			  PDO_ATTR_CLIENT_VERSION and PDO_ATTR_PERSISTENT attributes ]
+		 *			  - setAttribute		[ supports only PDO_ATTR_PERSISTENT modification ]
+		 *			  - lastInsertId		[ only fo PostgreSQL , returns only pg_last_oid ]
+		 *
+		 *	  - - - - - - - - - - - - - - - - - - - -
+		 *
+		 *	  PDOStatement :: UNSUPPORTED METHODS:
+		 *	  	- bindColumn 		[ is not possible to undeclare a variable and using global scope is not
+		 *			  			  really a good idea ]
+		 *
+		 *	  PDOStatement :: NOT TOTALLY SUPPORTED METHODS:
+		 *	  	- getAttribute		[ accepts only PDO_ATTR_SERVER_INFO, PDO_ATTR_SERVER_VERSION,
+		 *			  			  PDO_ATTR_CLIENT_VERSION and PDO_ATTR_PERSISTENT attributes ]
+		 *			  - setAttribute		[ supports only PDO_ATTR_PERSISTENT modification ]
+		 *			  - setFetchMode		[ supports only PDO_FETCH_NUM, PDO_FETCH_ASSOC, PDO_FETCH_OBJ and
+		 *			  			  PDO_FETCH_BOTH database reading mode ]
