Detailed Description

Divide a box into nx by ny sub-boxes that tile the region

The sub-boxes will be of the same type as `box` and will exactly tile `box`;
they will also all be the same size, to the extent possible (some variation
is inevitable for integer boxes that cannot be evenly divided.

Parameters
----------
box : `lsst.geom.Box2I` or `lsst.geom.Box2D`
    the box to subdivide; the boxes in the grid will be of the same type
numColRow : pair of `int`
    number of columns and rows
