Tables

Key Tables in HyperTable refers to the cross sections of the HyperTable at the points supplied as "first coordinates" in Coords.
In geometric terms, they represent data grids of dimensionality equalling that of the original HyperTable minus 1, that lie on hyperplanes that cross the first dimension axis at the "first coordinate" points at right angle.
Expected is an array of objects of type Table.
In the simplest 3D case, these will be objects of type Table2D, which represent regular 2-dimensional tables.
In the next in complexity 4D case, these will be 3D HyperTable objects, and so on.
