1. Check, if value found by math_PSO algorithm cannot be precised by math_NewtonMinimum algorithm. In this case, we call math_PSO algorithm repeatedly, however, with other parameters. 2. Some margin of edge tolerance value has been provided in IntTools_Tools class. 3. Interface of math_NewtonMinimum class has been changed (method GetStatus() has been added). Correction of some test cases according to their new behavior.
