Update UtilityFunctions.cs

allowing epsilon to be parameterized, default to Unity's Vector3.kEpsilon, which apparently is built into the Vector3 class specifically because Unity's representation of floats is the 32-bit variety and that epsilon value is tuned for that??? So seems like a good default still
