+ * Implementation for Excel REPT () function.<p/>

+ * <p/>
+ * Repeats text a given number of times. Use REPT to fill a cell with a number of instances of a text string.
+ *
+ * text : text The text that you want to repeat.
+ * number_times: A positive number specifying the number of times to repeat text.
+ *
+ * If number_times is 0 (zero), REPT returns "" (empty text).
+ * If this argument contains a decimal value, this function ignores the numbers to the right side of the decimal point.
+ *
+ * The result of the REPT function cannot be longer than 32,767 characters, or REPT returns #VALUE!.
