Follow Traditional Style Guide? (At least in public API)

[ParadaCarleton]

Some Soss functions follow weird capitalization conventions -- for instance, importanceSample is in lowerCamelCase instead of the traditional snake_case suggested by most Julia style guides (or the squashcase suggested by the official Julia guide). Do is similar -- could be renamed do_op to avoid conflicting with the do keyword.

JuliaFormatter might be a good option here.
