Setting doScan to false before calling start() will cause the RoverPOVScreen
to be completed as soon as the mission is completed, in other words, no scan
line will display and the final delay will be skipped.
Returns how long the action took to complete the last time it was
executed (in milliseconds), or how long the action is expected to
take if it has never been executed.
Acts as a liason between Sequencer and RoverPOVScreen so that the mission
status being displayed on screen matches the status of the the mission as
it is executed by the rover.
Contains the thread class for receiving and parsing
information returned by the rover during color tracking, mean
color detection, and motion detection as well as pictures taken during
turnTo and driveTo commands.
