"## Tiles, Blanks, and Racks\n",
"\n",
"Each tile has a single character on it, like 'W'. A rack is represented as a string of tiles, usually of length 7, such as \"EELRTTS\".\n",
"\n",
"Treating the blank is a little harder. From the notebook:\n",
"\n",
"> The blank tile causes some complications. We'll represent a blank in a player's rack as the underscore character, '`_`'. But once the blank is played on the board, it must be used as if it was a specific letter. However, it doesn't score the points of the letter. I chose to use the lowercase version of the letter to represent this. That way, we know what letter the blank is standing for, and we can distingush between scoring and non-scoring tiles. For example, \"EELRTT`_`\" is a rack that contains a blank; and \"LETTERs\" is a word played on the board that uses the blank to stand for the letter S.\n",
"\n",
"We define three helper functions:\n",
"\n",
"- `letters` gives all the distinct letters in a rack\n",
"- `remove` removes letters from a rack (i.e. after they have been played)\n",
"- `expandblanks` removes all blank `_` tiles from a string and adds the lowercase alphabet (that is, the letters that a blank can be converted to)."

(Think about the design of your program: is the bonus so fundamental to the character of the square that you want to have a bunch of different types called DoubleLetterSquare, StarSquare, and so on?
