+* EJERCICIO:
+ * Crea dos variables utilizando los objetos fecha (date, o semejante) de tu lenguaje:
+ * - Una primera que represente la fecha (día, mes, año, hora, minuto, segundo) actual.
+ * - Una segunda que represente tu fecha de nacimiento (te puedes inventar la hora).
+ * Calcula cuántos años han transcurrido entre ambas fechas.
+ *
+ * DIFICULTAD EXTRA (opcional):
+ * Utilizando la fecha de tu cumpleaños, formatéala y muestra su resultado de
+ * 10 maneras diferentes. Por ejemplo:
+ * - Día, mes y año.
+ * - Hora, minuto y segundo.
+ * - Día de año.
+ * - Día de la semana.
+ * - Nombre del mes.
+ * (lo que se te ocurra...)
