Check Skelton demo scene

What I did:

• track right hand
• calculate the delta time of current callback and previous callback
• calculate the delta position of current and previous callback
• calculate the vector by diving delta position with delta time
• send vector to VFX graph along the position
• some parameters are mapped to speed in VFX
