TwoDUtilTester.java

/**
* TwoDUtilTester has 3 methods public String shortest(), String lastColumn(), int howMany(char) which returns us shortest String in the 2d array, all strings in last column seperated by * and how many times a character appears in the array. These method works on the the 2D array provided.
