Creating the NumberGuesser class
Write your NumberGuesser class as if it is going to be used in many different guessing games, created by different developers. You want to create a class that will be a useful tool in different contexts.
When a new instance of a NumberGuesser class is instantiated the upper and lower bounds of the possible values should be passed into its constructor. From that point on a NumberGuesser object will always return the midpoint of the possible values when the getCurrentGuess() method is called.
If the higher() or lower() methods are invoked, the NumberGuesser object should adjust its state to represent the new possible range of values. For example, if a NumberGuesser is created with the following line of code then the range will be the numbers from 1 to 100:
NumberGuesser guesser = new NumberGuesser(1, 100);
If the getCurrentGuess() method is called it should return 50, which is the midpoint between 1 and 100. If the higher() method is invoked then the object should adjust its state accordingly so that it knows that the correct value is between 51 and 100. If the lower() method is invoked then it should adjust its state to represent that the possible values are between 1 and 49.
After that, the getCurrentGuess() should return the value that is in the middle of the new range of possible values. (Either 75 or 25). By following this strategy the number guesser should be able to eventually guess the proper value.
Here is the basic design of the NumberGuesser class that you should write. The instance variables have been left up to you.

The reset() method should return the NumberGuesser to the state that it was in when it was constructed. In order to do this your class will need to be able to remember its original state. You can use two additional instance variables to store the original upper and lower bounds. You might not need to invoke this method in your game for this project, but you will need to in later projects.
Write your number guess class and test it until you are sure that it is working properly. After it is working, write the rest of the program so that it plays the game by using an instance of your NumberGuesser class.
Note: Your NumberGuesser class should not use a Scanner object or System.out. It is only responsible for handling the indicated methods. All of the input and output work should be handled elsewhere in your program.
