Breaking changes

• All returned nodes are now forced to be at least epsilon apart, rather than
  allowing some to be the next allowable floating point number. This allows room
  for mutations. Epsilon has been changed to 1e-10 from 1e-6, to minimise the
  impact, as this has the potential to (marginally) change the dates of internal
  (fixed) sample nodes.

• Multiple mutations at the same site above the same node are now spaced out evenly
  in time, rather than placed at identical times.
