/**
 * Represents one of the rules of a Turing Machine.

 * The rule says that the machine will change to state newState, will
 * write newContent into the current cell on the tape, and will then move
 * eitehr to the left or to the right on the tape, depending on whether
 * the value of moveLeft is true or false.
