/* Further Adventures

 *

 * Let's change getGuesser to include a parameter

 * for setting the number of possible numbers to guess.

 *

 * e.g. getGuesser(20) will create random numbers

 * from 1 to 20. That's 20 possible numbers.

 *

 * 1) Add a 'range' parameter to the function

 *    definition of getGuesser.

 *

 *    var getGuesser = function (range) {

 *

 * 2) Change the 10 on line 7 to 'range'.

 *

 *    var secret = Math.floor(Math.random() * range + 1);

 *

 * 3) Include an argument when getGuesser is called

 *    on line 20.

 *

 *    var guess = getGuesser(20);

 *

 * 4) Test the game.

 *

 * 5) Now add a second parameter, 'offset'

 *    and update the code to choose random numbers

 *    greater than or equal to the value of offset.
