Changed getPositionIn(long) to getPositionIn(double) to allow for
fractional seconds.
Forgot to commit classpath file and settings after setting up junit
properly for eclipse.
Miscellaneous changes to PathPlanning and PathPlaningTest.  Committing
before rewriting the algorithm for arbitrary paths.
Added scalaTest as a dependency, moved and rewrote PathPlanningTest.

PathPlanning still doesn't work but at least I can write test cases for
it now.
