Added a static field that can be used to mark omnidirectional components that do not use field relativeOrientation.
Restored this directory.
Fixed some bugs.  Vibration sensor now approximates frequency, has a gaussian noise for amplitude an frequency.
QuadraticVibrationSource marked has omnidirectional.
Added two bee behaviours.  Bees can climb light or vibration gradients.
Bees can have a behaviour based model.
Light sensors can also be omnidirectional.
Added a program to test vibration sensors and sources.  Updated changes to constructors.
