/**
 * @defgroup KinematicFamily Kinematic Families
 * @brief All classes to support kinematic families.
 *
 * The Kinematic Families classes range from the basic building blocks
 * (KDL::Joint and KDL::Segment) and their interconnected kinematic
 * structures (KDL::Chain and KDL::Tree), to the solver
 * algorithms for the kinematics and dynamics of particular kinematic
 * families.
 *
 * A <em>kinematic family</em> is a set of kinematic structures that have
 * similar properties, such as the same interconnection topology, the same
 * numerical or analytical solver algorithms, etc. Different members of the
 * same kinematic family differ only by the concrete values of their
 * kinematic and dynamic properties (link lengths, mass, etc.).
 *
 * Each kinematic structure is built from one or more Segments
 * (KDL::Segment). A KDL::Chain is a <strong>serial</strong> connection of
 * these segments; a KDL:Tree is a <strong>tree-structured</strong>
 * interconnection; and a KDL:Graph is a kinematic structure with a
 * <strong>general graph</strong> topology. (The current implementation
 * supports only KDL::Chain.)
 *
 * A KDL::Segment contains a KDL::Joint and an offset frame ("link length",
 * defined by a KDL::Frame), that represents the geometric pose
 * between the KDL::Joint on the previous segment and its own KDL::Joint.
 *
 * A list of all the classes is available on the modules page: \ref KinematicFamily
