X-HD: Fast Hausdorff Distance Computation with Ray Tracing

---

Example

./bin/hd_exec \
    -input1 "file path1" \
    -input2 "file path2" \
    -n_dims "number of dims" \
    -input_type "image/wkt/ply" \ # image is for the MRI images, wkb is for the geospatial datasets, and ply is for the graphics datasets
    -variant "eb/nn/itk/rt" \ # rt is the X-HD algorithm in the paper
    -execution "cpu/gpu" \ # cpu is for the CPU implementation, and gpu is for the GPU implementation. RT only has the GPU implementation.
    -v=1
