Like the Physbone and Contact components, I believe the new Raycast component could benefit from having it write a couple parameters to the animator. These parameters would help simplify some setups that already exist which use constraints and contacts to get similar information out of FinalIK raycasts.

Name below is the name given by the user for the parameter name similar to how it's done for Physbones.

Name_Ratio - Ratio of (Current Raycast Distance/Max Raycast Distance)

Name_Distance - Current distance of raycast

Name_Colliding - Boolean that returns true when raycast is colliding with something.

If anyone else has any parameters that they would like to suggest feel free to write in the comments.
