Add two test cases. test_size is showing the size of public and internal

2003-03-05  Martin Schulze  <MHL.Schulze@t-online.de>

	* tests/Makefile.am, tests/test_size.cc, tests/test_accumulated.cc:
	Add two test cases. test_size is showing the size of  public and
	internal structures. (Which apart from empty signals are smaller
	than the sizes of the equivalent libsigc++-1.2 structures.)
	test_accumulated is a test for the template signal<>::accumulated<>
	at the same time showing the use of accumulators in libsigc++2.
