copyTwoDimBoolArray

This is a helper method for you to use in the getters and setters for visited and blocked. Since all four of those methods require making a copy of a two dimensional boolean array, it is good for us to make that a helper method so that we do not need to duplicate code.

This method should create a new two dimensional array of booleans that is the same size as the argument passed to it$.$

It should then copy every value from the provided two dimensional array into the new one.
