/**
 * Processes streams in the Horrible Property Set Format (HPSF) in POI filesystems.
 * Microsoft Office documents, i.e. POI filesystems, usually contain meta data like author, title,
 * last saving time etc. These items are called <strong>properties</strong> and stored in
 * <strong>property set streams</strong> along with the document itself.
 * These streams are commonly named {@code \005SummaryInformation} and {@code \005DocumentSummaryInformation}.
 * However, a POI filesystem may contain further property sets of other names or types.
 * <p>
 * In order to extract the properties from a POI filesystem, a property set stream's contents must be parsed into a
 * {@link org.apache.poi.hpsf.PropertySet} instance.  Its subclasses {@link org.apache.poi.hpsf.SummaryInformation}
 * and {@link org.apache.poi.hpsf.DocumentSummaryInformation} deal with the well-known property set streams
 * {@code \005SummaryInformation} and {@code \005DocumentSummaryInformation}.
 * (However, the streams' names are irrelevant. What counts is the property set's first section's format ID - see below.)
 * <p>
 * The factory method {@link org.apache.poi.hpsf.PropertySetFactory#create} creates a PropertySet instance.
 * This method always returns the <strong>most specific property set</strong>:
 * If it identifies the stream data as a Summary Information or as a Document Summary Information it returns an
 * instance of the corresponding class, else the general PropertySet.
 * <p>
 * A PropertySet contains a list of {@link org.apache.poi.hpsf.Section Sections} which can be
 * retrieved with {@link org.apache.poi.hpsf.PropertySet#getSections}. Each Section contains a
 * {@link org.apache.poi.hpsf.Property} array which can be retrieved with
 * {@link org.apache.poi.hpsf.Section#getProperties}. Since the vast majority of PropertySets contains only a single Section,
 * the convenience method {@link org.apache.poi.hpsf.PropertySet#getProperties} returns the properties of a
 * PropertySets Section (throwing a {@link org.apache.poi.hpsf.NoSingleSectionException} if the PropertySet contains
 * more (or less) than exactly one Section).
 * <p>
 * Each Property has an <strong>ID</strong>, a <strong>type</strong>, and a <strong>value</strong> which can be
 * retrieved with {@link org.apache.poi.hpsf.Property#getID}, {@link org.apache.poi.hpsf.Property#getType},
 * and {@link org.apache.poi.hpsf.Property#getValue}, respectively. The value's class depends on the property's type.
 * <!-- FIXME: --> The current implementation does not yet support all property types and restricts the values' classes
 * to String, Integer and Date. A value of a yet unknown type is returned as a byte array containing the values
 * origin bytes from the property set stream.
 * <p>
 * To retrieve the value of a specific Property, use {@link org.apache.poi.hpsf.Section#getProperty} or
 * {@link org.apache.poi.hpsf.Section#getPropertyIntValue}.
 * <p>
 * The SummaryInformation and DocumentSummaryInformation classes provide convenience methods for retrieving well-known
 * properties. For example, an application that wants to retrieve a document's title string just calls
 * {@link org.apache.poi.hpsf.SummaryInformation#getTitle} instead of going through the hassle of first finding out
 * what the title's property ID is and then using this ID to get the property's value.
