constrain variables to integers

[wvanderp]

Hello,

In my use case, the only solutions that make sense are integers.

Think X plates of 3 kg + Y blocks of 12.5 kg for 27 kg
which would result in either of two solutions:

1 3 + 2 * 12.5 = 28 (1 kg over)
or
03 + 2* 12,5 = 25 (2 kg under)

But I currently see no way to do this with the library.

My questions are as follows:

Do you think this can be done with the current lib?
Is it trivial to add? (AKA, do you recommend me to send a PR)
Am I on a totally wrong path and do I need to use a different lib?

looking forward to your thoughts
