* \brief N-dimensional gaussian spatial function class
*
* GaussianSpatialFunction implements a standard gaussian curve in N-d.
* m_Normalized determines whether or not the Gaussian is normalized
* (whether or not the sum over infinite space is 1.0)
*
* m_Scale scales the output of the Gaussian to span a range
* larger than 0->1, and is often set to the maximum value
* of the output data type (for instance, 255 for uchars)
