/*-------------vortex_3d.cu---------------------------------------------------//
*
* Purpose: This file intends to perform a convolution of 3d data for vortex
*          recognition in the GPUE code
*
*   Notes: We will be using the window method for convolutions because it has
*          a slightly better complxity case for a separable filter
*          (which the Sobel filter definitely is!)
