Switch from "promises" to "accepting set". Fix the definitions

Browse source 
of these accepting set so that they are really usable.  Provide
a all_accepting_conditions() method for use in the emptyness
check, and a neg_accepting_conditions() for products.
Predeclare TGBA accepting conditions is the i/o.
