On branch 'svn-bisect': Add notes, initial algorithm to BRANCH-README

* BRANCH-README
  Expand this file considerably, primarily with thoughts and a
  description of an initial algorithm. In particular, the focus is on
  implementing a bisect algorithm that handles 'skipped' revisions,
  both implicitly skipping revisions that do not touch the branch
  being bisected, and explicitly skipping revisions when so instructed
  by the user, e.g., when a revision cannot be tested because the
  build was broken in that revision.
