Wrong border 1.0e-9 jump has deleted. Added periodicity information when projecting to surface. Period "jump" bug fixes. AppCont_LeastSquare conversion to non cdl class. AppCont_Function + AppCont_FunctionTool combined in one class providing the same functionality and converted to non cdl. Testcase modification. Test cases for issue CR24988 Fixed incorrect comparison.
