Use branching call system to avoid callstack overflow #13
Description
Each state transition currently expands a symbol one step deeper in the tracery call stack. This may cause stack overflows in machines that use many steps. Eli Dupree has made a prototype of a branching call system which doubles the number of execution steps every two levels deeper in the call stack. It requires an exit method before it can be used.
