SkewFolder

A triple wavefolder with variable topology that provides the ability to move between different combinations of the skew and fold stages.

There are noticeable differences between putting the skew stage before, after, or between the fold stages.

Key parameters are audio rate controllable.

The single fold design is by Pete. Extensions and final topology by Alan and Ben.

Note:  This folder is a major improvement over prior implements like the FlipWrap so those have been deprecated in the Library.
