In essence, the DeBruijn table provides a set of values for a table lookup which makes finding Log2 of the provided value faster as it takes less operations to perform.

In the future we'll be switching to the hardware intrinsic/asm instruction, but that is fiddly in C++, and so this software implementation was created.
