TypeLift Rejiggering

:warning:  This pull-request is *massive* and *will* break lots of things. :warning: 

This moves the foundation of Swiftz onto the Basis so control can be transferred to [TypeLift](https://github.com/TypeLift) ASAP.  APIs previously relating to basic algorithms and data structures have been moved into the [Basis](https://github.com/typelift/Basis).  Concurrency Primitives have been moved into the [Parallel](https://github.com/typelift/Parallel) package.  Further splitting and refinement of Swiftz will continue as the Swift language advances and more structures are included.
