/**
 * @ingroup Graph
 * @brief This class extends upon PropertyInterface, and adds type-safe methods to
 * get and set the node and edge values, through the magic of template programming.
 *
 * Nodes and Edges can have different types (e.g. tlp::LayoutProperty has tlp::PointType as node
 * type and tlp::LineType as edge type),
 * but most of the time they have the same type (e.g. tlp::DoubleProperty, tlp::IntegerProperty).
 *
 * Some of the pure virtual functions of PropertyInterface are implemented in this class (e.g.
 * erase()).
 *
 * The actual data is stored in this class, and it manages the default values.
