Testing Random Module Functionality with Nose Library

This function uses tools from the nose library to test the functionality of the random module. It accepts two arguments, if both arguments are None, it tests whether two randomly generated numbers are equal; if the first argument is not None, it tests whether the generated random number is greater than the first argument; if the second argument is not None, it tests whether the generated random number is less than the second argument; if both arguments are not None, it tests whether the generated random number is equal to the values of both arguments.
