Allows for fading in (or out) of the bolt with time. Can also create a "projectile" bolt
Recommend setting AnimationSpeed to 0 if used as projectile (for better aesthetics)
Works by passing a "wave" function which travels from left to right where the wave height represents opacity (opacity being 1 - Transparency)
See https://www.desmos.com/calculator/hg5h4fpfim to help customise the shape of the wave with the below properties

--[[
Allows you to pass a custom space curve for the bolt to be defined along
Constraints:
-First input passed must be a parameter representing PercentAlongBolt between values 0 and 1
Example: self.SpaceCurveFunction = VivianiCurve(PercentAlongBolt)
--]]
self.SpaceCurveFunction = CubicBezier
--[[
Allows you to pass a custom opacity profile which controls the opacity along the bolt
Constraints:
-First input passed must be a parameter representing PercentAlongBolt between values 0 and 1
-Second input passed must be a parameter representing TimePassed since instantiation
Example: self.OpacityProfileFunction = MovingSineWave(PercentAlongBolt, TimePassed)
Note: You may want to set self.ContractFrom to a value above 1 if you pass a custom opacity profile as contraction was designed to work with DiscretePulse
--]]
self.OpacityProfileFunction = DiscretePulse
--[[
Allows you to pass a custom radial profile which controls the radius of control points along the bolt
Constraints:
-First input passed must be a parameter representing PercentAlongBolt between values 0 and 1
