The authors of this library are Ovidiu Predescu Mircea Oancea . We would like to thanks to Florin Mihaila for his ideas and for his support in putting our work in public domain and to Mihaela Mihaila, Stefan Popescu, Claudiu Cruceanu, Calin Gatina and Bogdan Baliuc for their work in the old library and for removing all those nasty bugs :-)!
