+ * This class works like an array.
+ * The internal array is constructed from a comma separated string
+ * When used in an string context, it is automatically converted to a comma
+ * separated string
+ *
+ * Usage:
+ * @code
+ * $csvarray = new CSVArrayObject('eins,zwei,drei');
+ * $csvarray[] = 'vier';
+ * echo $csvarray; // prints out "eins,zwei,drei,vier"
+ * @endcode
