How to set mutation and cross over probability?

[sandcobainer]

No examples or documentation about setting mutation rate or cross over probability? I'm pretty sure you must have thought about this while writing a Genetic Algorithm framework.

If possible add it to the README.md or examples.

From looking at the code, it doesn't seem to be possible. I just realized this so it looks like I'm going to have to use a different library.
