/** CLASS Piezas
 * Class for representing a Piezas vertical board, which is roughly based
 * on the game "Connect Four" where pieces are placed in a column and 
 * fall to the bottom of the column, or on top of other pieces already in
 * that column. For an illustration of the board, see:
 *  https://en.wikipedia.org/wiki/Connect_Four
 *
 * Board coordinates [row,col] should match with:
 * [2,0][2,1][2,2][2,3]
 * [1,0][1,1][1,2][1,3]
 * [0,0][0,1][0,2][0,3]
 * So that a piece dropped in column 2 should take [0,2] and the next one
 * dropped in column 2 should take [1,2].

 * Constructor sets an empty board (default 3 rows, 4 columns) and 
 * specifies it is X's turn first

 * NOT allow to place a piece in a location where a column is full.
 * In that case, placePiece returns Piece Blank value 
 * Out of bounds coordinates return the Piece Invalid value
 * Trying to drop a piece where it cannot be placed loses the player's turn

/**
 * Returns which Piece has won, if there is a winner, Invalid if the game
 * is not over, or Blank if the board is filled and no one has won ("tie").
 * For a game to be over, all locations on the board must be filled with X's 
 * and O's (i.e. no remaining Blank spaces). The winner is which player has
 * the most adjacent pieces in a single line. Lines can go either vertically
 * or horizontally. If both X's and O's have the same max number of pieces in a
 * line, it is a tie.
