Refactored Scala code out of build.sbt and away into project/Build.scala.
Fixed bug when entering malformed agent/rig for "into" command.
Starting to put type safety around agent and port strings.
Radical reworking, putting lots of type safety in, replacing Strings
with PortIDs and Agents. Replaced List[String] with Pos. Compiles, but
tests unlikely to run.
Lots of tests passing, but quite a few failing. Contains println
debugging.
All tests pass; lots of println debugging to remove.
All tests pass; println debugging removed.
