Re-write or delete SensorManager

[chlohal]

Whether you re-write or delete is up to whoever takes this issue. Either solution is equally justified-- deleting it cleans up our codebase, and re-writing gives more utility to future years.

If you Decide to Re-Write

• [x] Move the ColorSensor helper class from the auxilliary package into the managers/sensor package
• [x] Move the general Sensor super-class from auxilliary to managers/sensor.
• [x] Make the general Sensor super-class have a few methods-- isSpecial() especially!
• [x] Brainstorm -- what are some things that all sensors have in common? ("getNumberValue()", "getFloatArray()", etc. don't be afraid to stretch it; we already have isSpecial()) Add them to Sensor as abstract methods.
• [x] Add a quick implementation of the general common methods to ColorSensor
• [x] Add javadoc comments in SensorManager! (`/`)**

Rewrote the issue to only contain the rewrite tasks, as I chose to rewrite SensorManager instead of deleting it.

All tasks involving the rewrite are complete, SensorManager now differentiates between colorSensors, touchSensors, and distanceSensors similarly to ManipulationManager's differentiation between DCMotors, Servos, and CRServos.
