it was confusing getPositionCopy and getLastPosition so I made them more
explicit; now, getPosition() (was getLastPosition) will return the postion
from the last positionSnapshot() (which returns nothing, just copies the
volatile position into pCopy so that getPosition will read from it;)
snapshot is called once in the timedOut of Robot, so you just need to call
getPostition
slowly javadocing
