/// \brief Functions to compute bounds for a dataset or multiblock
///
/// These are utility functions that compute bounds for the dataset or
/// multiblock. When VTK-m is operating in an distributed environment, these
/// are bounds on the local process. To get global bounds across all ranks,
/// use `vtkm::cont::BoundsGlobalCompute` instead.
///
/// Note that if the provided CoordinateSystem does not exists, empty bounds
/// are returned. Likewise, for MultiBlock, blocks without the chosen CoordinateSystem
/// are skipped.
