ConeCastAll extension method
A Unity3d ConeCastAll extension method for the Physics class.
Use this to find colliders within a cone-shaped volume.
It uses SphereCastAll, which is like a RayCast tube, but then it uses Vector3.Angle to filter out hitpoints according to a cone.
Using it is very similar to using SphereCastAll.
Variables: Vector3 origin, float maxRadius, Vector3 direction, float maxDistance, float coneAngle
