	* <p>Controls {@code String} formatting for {@link ToStringBuilder}.
	* The main public interface is always via {@code ToStringBuilder}.</p>
	*
	* <p>These classes are intended to be used as {@code Singletons}.
	* There is no need to instantiate a new style each time. A program
	* will generally use one of the predefined constants on this class.
	* Alternatively, the {@link StandardToStringStyle} class can be used
	* to set the individual settings. Thus most styles can be achieved
	* without subclassing.</p>
	*
	* <p>If required, a subclass can override as many or as few of the
	* methods as it requires. Each object type (from {@code boolean}
	* to {@code long} to {@code Object} to {@code int[]}) has
	* its own methods to output it. Most have two versions, detail and summary.
	*
	* <p>For example, the detail version of the array based methods will
	* output the whole array, whereas the summary method will just output
	* the array length.</p>
	*
	* <p>If you want to format the output of certain objects, such as dates, you
	* must create a subclass and override a method.
	* </p>
