Improved vps calibration routines for getting points and getting unit relationships.
Fixed nasty typo in go_to that caused distance to be miscalculated.
Moved MIN_SPEED def to header to allow capture routine to make use of it.
Updated waypoints using VPS to account for new drift.
Improved debugging for sensor system.
Recalibrated conversion factor for vps and ticks.
Added function to get the average current draw of both drive motors, for use in detecting obstructions.
Added space to manager header for AI functions.
Experimental data for alternative distance sensor. Still a garbage sensor.
Updated waypoint data in format for easy gnuplot graphing.
