GitLab

  Parsing doxytag files make recent versions of doxygen run into an infinite
  loop.

  - move fcl forward declarations to fcl,
  - create doxygen link to fcl documentation.

  - notify copyright outside doxygen,
  - remove obsolete tags.

  - remove dependency to
     - Kitelab and
     - jrl-dynamics
  - add dependency to fcl,
  - implement class Body as fcl::CollisionObject container,
  - implement forward kinematics.

    Add a page with explanation on porting client code,
    Document some classes.

    Use cmake,
    Make joint classes derive from Kineo and jrl-dynamics corresponding joint
    classes.
