/*
* Struct that allows applying morph targets data to an arbitrary skinned mesh component
* instead of relying on the skeletal mesh component.
* 
* Usage - In a tick method of your choosing:
* 1) ResetMorphTargetCurves(Component) at the start of the update.
* 2) SetMorphTarget(...) as many times as needed based on your data set.
* 3) ApplyMorphTargets(Component) at the end of the update to apply the morph targets to the anim runtime.
