INTEGRATION: CWS stliterators (1.1.2); FILE ADDED

2008/05/08 16:41:45 b_michaelsen 1.1.2.4: made ::comphelper::StlUnoSequence const-correct
2008/05/08 11:08:02 b_michaelsen 1.1.2.3: taking parameters by reference, not a pointer
2008/05/08 10:38:51 b_michaelsen 1.1.2.2: added convenience functions ::comphelper::stl_begin and ::comphelper::stl_end in stlunosequence.hxx and updated some tests
2008/05/08 09:08:13 b_michaelsen 1.1.2.1: simple testcase for ::comphelper::StlUnoSeuqence
