Consider pulling in a fugue-steps module

[Matthew McMahon]

See https://bitbucket.org/maccamlc/fugue-steps/src/master/

Should the FunctionN (6) be added in this module, or something else?

[Anund McKague]

Initial questions without deep review: Can we use java's built in function for function1? Perhaps we should name this fugue extentions? other code that might want to use functionN can end up in that module perhaps?

[Anund McKague]

Following on the extensions comment we would then have a steps package?

What is intended to end up in the ops package?
