// Language   : Java
// Description: This program checks to see if 3 numbers input by the user
//              represents a triangle and if so what sort of triangle
//
// Test Data  : 1 2 3 - not a triangle
//              1 1 1 - equilateral
//              3 4 5 - right angle triangle
//              3 2 2 - isosceles
//              3 3 2 - isosceles
//              4 5 6 - scalene
