Minor change - formating
Minor changes: Upgraded documentation and formating
Joints:
Revolute joint: Enabled conditional animation of black line to highlight joint rotation (parameter extraLine).
Both joints: (1) All animation parameters collected in "group" animation, since there is just a few parameters otherwise; (2) In icon: added description of frame "a" and "b"; (3) Upgraded documentation.
Icons only: Introduced description of frame "a" and "b" if reasonable
