classdef BoardPiece < handle
%BoardPiece is an abstract class that takes two inputs, a position and a
%board. It has a constructor that assigns the position to the Position
%property, and board to the MyBoard property. It has a die method which
%takes the current position and board of a block, and replaces it with an
%EmptySpace object. Finally, it has an abstract method getSym, which
%acquires a two-letter string depending on the type of block it is.
