Title: Couple of fixes

Hi Rutger,
I have noticed an of issues with the calc_*_distance methods: when calculating the distance between a node and itself, the distance was larger than 0. This is partially due to a bug in get_mrsa. Luckily, it was not very hard to track down and fix. See attached commits. Enjoy,
Florent
