    Welcome to the binary search tree program! This program will set 
    up a binary search tree with a set of random numbers in the range 
    -20..20 and will attempt to find a random number in the tree before 
    attempting to delete a random number from the tree. This process will
    be executed twice to thoroughly test the procedures used. Enjoy!
    
    Filling the binary search tree with a new set of random numbers...
    Putting 13 in the tree.
    Putting -4 in the tree.
    Putting 4 in the tree.
    Putting -6 in the tree.
    Putting -18 in the tree.
    Putting -7 in the tree.
    Putting 7 in the tree.
    Putting 6 in the tree.
    Putting -3 in the tree.
    Putting 20 in the tree.
    Putting -11 in the tree.
    Putting -2 in the tree.
    Putting -18 in the tree.
    This number is already in the tree, no change.
    Putting -12 in the tree.
    Putting -18 in the tree.
    This number is already in the tree, no change.
    Putting 9 in the tree.
    Putting 3 in the tree.
    Putting 0 in the tree.
    Putting -1 in the tree.
    Putting -15 in the tree.
    
    This is what an in-order traversal of the tree looks like:
      -18
      -15
      -12
      -11
       -7
       -6
       -4
       -3
       -2
       -1
        0
        3
        4
        6
        7
        9
       13
       20
    
    This is what a pre-order traversal of the tree looks like:
      -15
      -12
      -11
       -7
      -18
       -6
       -1
        0
        3
       -2
       -3
        6
        9
        7
        4
       -4
       20
       13
    
    This is what a post-order traversal of the tree looks like:
       13
       -4
       -6
      -18
       -7
      -11
      -12
      -15
        4
       -3
       -2
        3
        0
       -1
        7
        6
        9
       20
    
    Searching for -2
    Was the number found? TRUE
    
    Attempting to delete from the tree: 13
    The delete was successful.
    
    Attempting to delete from the tree: 20
    The delete was successful.
    
    Attempting to delete from the tree: 9
    The delete was successful.
