/**
 * <p>{@link BeanUtilsBean} implementation that creates a
 * {@link ConvertUtilsBean2} and delegates conversion to
 * {@link ConvertUtilsBean#convert(Object, Class)}.
 * </p>
 *
 * <p>
 * To configure this implementation for the current context ClassLoader invoke
 * {@code BeanUtilsBean.setInstance(new BeanUtilsBean2());}
 * </p>
 *
 * <p>
 * BeanUtils 1.7.0 delegated all conversion to String to the converter
 * registered for the {@code String.class}. One of the improvements in
 * BeanUtils 1.8.0 was to upgrade the {@link Converter} implementations so
 * that they could handle conversion to String for their type (e.g.
 * IntegerConverter now handles conversion from an Integer to a String as
 * well as String to Integer).
 * </p>
 *
 * <p>
 * In order to take advantage of these improvements BeanUtils needs to change
 * how it gets the appropriate {@link Converter}. This functionality has been
 * implemented in the new {@link ConvertUtilsBean#lookup(Class, Class)} and
 * {@link ConvertUtilsBean#convert(Object, Class)} methods. However changing
 * {@link BeanUtilsBean} to use these methods could create compatibility
 * issues for existing users. In order to avoid that, this new
 * {@link BeanUtilsBean} implementation has been created (and the associated
 * {@link ConvertUtilsBean2}).
 * </p>
 *
 * @see ConvertUtilsBean2
 * @since 1.8.0
