1.  Make an aspect PrintFirstArgs that is activated when
    a method in class Test is called that has at least one parameter.
    The aspect should print the first parameter's value on the command line.

    What happens if you direct your advice in the aspect
    towards any class instead of limiting it to Test?

2. 	Using the CallerCallee aspect,
	count how many method calls in the code is such that
	the caller object and the callee object are the same.
	For each such call, print the counter's current value to the standard output.

3.  Make an aspect ExceptionLog that logs into a file
    each exception that the program throws.
    The caller object and the exception instance should be printed into the file
    on each throw.
