Performs linear interpolation in arbitrary dimensions. The class is non-owning and expects a C-ordered array, (n, x, y, z). The variable index, n, varies fastest in memory. Note that this class is intentionally non-pupable. More...

Performs linear interpolation in arbitrary dimensions. The class is non-owning and expects a C-ordered array, (n, x, y, z). The variable index, n, varies fastest in memory. Note that this class is intentionally non-pupable.
| Dimension | dimensionality of the table |
| NumberOfVariables | number of variables stored in the table |
| UniformSpacing | indicated whether the table has uniform _spacing or not. This is useful for performance reasons in finding the appropriate table index. |
