Message:

Extensive changes to the way spatial variation of the kernel is implemented. I was doing it the stupid way, rather than the smart way outlined in Alard 2000 (A&ASS, 144, 363). Fixed up the normalisation of the kernels (essential for proper flux conservation with spatial variation). Put in support for dividing an image up into regions.
