started collections, but there is a serious problem.
added mux combinator
various independently implemented muxes
unified mux, at cost of performance somehwat.
more dynamic collections...all unsaveable, how sad.
organized Collection up a bit, now to refactor
new muxI
added mux1
added muxF family
added muxI and muxFI.  lots of functions though.
changes to Event; rewriting to use combinators and also new event manipulators
unfold generator
new collections
finished out Gather family.  lots of duplicates.
switchF internal switch
external switch
various delays
more switches; laid out.
Major additions of Collection and Switch, with some minor edits to various
things to simplify things.
