/// \brief Clamps boundary values to the nearest valid i,j,k value

/// BoundaryClamp always returns the nearest valid i,j,k value when at an
/// image boundary. This is a commonly used when solving differential equations.
///
/// For example, when used with WorkletCellNeighborhood3x3x3 when centered
/// on the point 1:
/// \code
///               * * *
///               * 1 2 (where * denotes points that lie outside of the image boundary)
///               * 3 5
/// \endcode
/// returns the following neighborhood of values:
/// \code
///              1 1 2
///              1 1 2
