[sr-dev] New: max branches configurable via parameter

[Robert Boisvert]

My team is very interested in this solution so I tried to size up the
effort.  My analysis revealed it would take a major redesign to support
this since many static structures, like struct cell, depend on it.  If I'm
wrong, we would really like to see this changed to dynamic.
