Experiments on binary and linear search
---------------------------------------


 1. Have a look at the slides binSearch.ppt

 2. Also, Growth.java for growth rates (then use gnuplot)
    Edit out comments for 2^n, 3^n and n!

 3. Test.java shows binSearch working
    Reads in a sorted unix dictionary, because it is mix of lower
    and upper case it had to be sorted. 
    Show how it finds something and how it shows absence by low & hi cross over
