Seven methods for generation of random Latin Squares

This version includes the implementation of seven techniques to generate random Latin Squares that are approximately uniformly distributed.

It provides a main executable class that allows for the generation of LSs of any order from a system console using a generated runnable JAR file. You can pass the algorithm's name and order of the Latin Square to the main method and also if you a path if you want to write the result into a text file. Just type: "java -jar generator.jar" for help.

In addition, full javadoc comments are provided to guide the API user in every public method. This allows the generation of useful javadoc documentation in HTML of every public class and interface.
