Odorant Sphere

Add a Sphere component to any game-object you want to possess a radially based odor. When the Olfactory Epithelium is found within the inner radius, maximum activation of the odorant occurs. When the Olfactory Epithelium is found outside the outer radius, no activation occurs. When the Olfactory Epithelium is found between the two, Radial Scaler augments how the intensity of the odor increases from the outer radius to inner radius, that way designers are not limited to a liner intensity ramp. Note: Radial Scaler will typically start at [0.0, 1.0] and end at [1.0, 0.0]
