Draws Textual Histogram / BarGraph from an Integer Array

				
//**************************************
// Name: Draws Textual Histogram / BarGraph from an Integer Array
// Description:Produces a textual representation of the data in an integer array. It efficentely and compactly counts the occurences of each value, converts it to a percentage and dispays it graphically.
// By: Zach Bastick
//
// Inputs:An integer array (e.g. int[], or ArrayList<Integer>), the minimum value in array and the maximum value in the array (for graphing purposes).
//
// Returns:An illustration similar to this:
1.36%	10	|xx
3.52%	9	|xxxx
3.27%	8	|xxxx
8.12%	7	|xxxxxxxxx
10.91%	6	|xxxxxxxxxxx
13.12%	5	|xxxxxxxxxxxxxx
14.6%	4	|xxxxxxxxxxxxxxx
14.69%	3	|xxxxxxxxxxxxxxx
12.74%	2	|xxxxxxxxxxxxx
10.62%	1	|xxxxxxxxxxx
6.98%	0	|xxxxxxx
total: 11776
