/**
 *  @brief A object with properties template
 *
 *  This template provides some kind of "enhanced shape". A shape can be supplied
 *  with additional properties. For performance reasons, the properties are stored
 *  as an index within a lookup table. Each index refers to a set of properties.
 *  The "PropertiesRepository" class manages the properties available and associates
 *  a property set with an index. 
 *  The shape-with-properties template adds the properties repository index to a 
 *  shape and inherits all of the shape's methods.
 *  This template is not confined to be used with shapes. It can be used for
 *  instances as well.
