+ *
+ * @param scanner       The scanner.
+ * @param begin_quotes  The character array to begin the quotes. For example,
+ *                      the two characters " and '.
+ * @param end_quotes    The character array to end the quotes. The position
+ *                      found in the begin_quotes array will be used to match
+ *                      the end quotes. So if the begin_quotes was the array
+ *                      of "'< the end_quotes should be "'>. If begin_array
+ *                      matched the ' then the end_quotes will look for ' to
+ *                      match at the end.
+ * @param qsize         The size of the begin_quotes and end_quotes arrays.
+ * @param out           String to store the result.
