Time for action – GamePiece class methods – part 1 – updating

1. Add the following methods to the GamePiece class:

   Public Sub SetPiece(type As String, suffix As String)
     _pieceType = type
     _pieceSuffix = suffix
   End Sub
   
   Public Sub SetPiece(type As String)
     SetPiece(type, "")
   End Sub
   
   Public Sub AddSuffix(suffix As String)
     If Not _pieceSuffix.Contains(suffix) Then
       _pieceSuffix &= suffix
     End If
   End Sub
   
   Public Sub RemoveSufix(suffix As String)
     _pieceSuffix = _pieceSuffix.Replace(suffix, "")
   End Sub

   The first two methods are overloads with the same name, but different parameter lists. In a manner similar to the GamePiece constructors, code that wishes to update a GamePiece can pass it a piece type and, optionally, a suffix.

   Additional methods have been added to modify suffixes without changing the pieceType associated with the piece. The AddSuffix() method first checks to see if the piece already contains the suffix. If it does, nothing happens. If it does not, the suffix value passed...
