Remove gaussian sampling, prevent 0-mass weibull samples

[RainierBarrett]

Addresses #23, at least for now. Worth thinking about how big of the edge effect converting samples of 0 to 1 really has.

Looks good to me. I think we just need to remove the Gaussian unit test at the bottom of test_systems.py

@RainierBarrett Did you see my comment about removing the Gaussian unit test?

Also, if this PR is going to merge in the branch of another open PR, maybe it would make more sense, and be a lot easier to keep track of everything if we close one of them, and only have one PR.

51 fixed the Gaussian sampling issue.
