I have a group of numbers that need to be distributed into four groups so
that the sum of the numbers in each of the four groups is as equal as
possible.

E.G., if I had this group of numbers: 26, 45, 99, 33, 45.5, 66.67, 15,
110.15 & 76.33

how would I break these 9 numbers into 4 groups so that each of the groups
had a sum as close as possible to the other groups?
