IK Foot

This addon simulates Inverse Kinematics algorithm for player legs, like on NPC legs.

• Realistic legs behavior
  
• Сompatibility with any animations.

• player_ik_foot
  - enable/disable inverse kinematic for foot. 1 – on, 0 – off (def. 1)
  
• player_ik_foot_lean
  - enable/disable player movement with additional leaning. 1 – on, 0 – off (def. 0)
  
• player_ik_foot_ground_distance
  - max collision distance feet with an obstacle. (def. 45)
  
• player_ik_foot_smoothing
  - animation smoothing. (def. 17)
  
• player_ik_foot_debug
  - enable/disable display debug tools. 1 – on, 0 – off (def. 0)

This is not a complete implementation IK, due to problems with bones manipulation and need to support custom animations - all calculations are approximate. Because of this, the algorithm may work incorrectly in some places. Fortunately, probability of this is minimal.
