Merge #177

177: Resolve scikit-learn conflict r=tsj5 a=tsj5

# PULL REQUEST

## Purpose and Content
This PR fixes the problems encountered by `@szy21` in #175. The purpose of that PR was to update the Manifest for the examples (Project/Manifest for CES itself is unchanged). This PR uses `@szy21` 's updates and in addition pins the versions of scipy and scikit-learn installed through Conda.jl to avoid an incompatibility in libstdc++ (documented in #176).

## Benefits and Risks

**Benefits**: Resolves #176. `@szy21's` original PR resolves #174.

**Risks**: Introduces maintenance requirement of having to remember we've pinned the versions of some dependencies going forward; since these are python dependencies this information isn't in Project.toml, so we might forget about this in the future when we want/need to update scikit-learn. This is a very minor risk, as the functionality from sk-learn that we currently use is mature.
