Mummer needs to be installed, so that these executables are in your $PATH: nucmer, show-coords, show-snps, delta-filter.

Mummer is available here:
https://github.com/mummer4/mummer/releases

Fixed in #40

Can now install without mummer deps present in $PATH. Pymummer will raise an error upon import if deps are not found.
