Add a new page that explains testing functions that use random generator #64

Give an example showing how to make a MockRng struct and use it instead, providing a default RNG as well as recommended in https://github.com/rust-random/rand/issues/1319.

Feel free to change the explanation or edit the code or leave feedback.

One problem with this solution is that if there are multiple tests that require different values, it won't work. The Default trait can be implemented only a single time.

Made the requested changes. Thanks for the comments.
