Marshaller CLR nie rozumie STLowych stringow, tylko BSTR albo LPSTR /

Jesli ten DLL jest Twoj, to przepisujac go, tak zeby funkcje wolane z C# 
uzywaly parametrow strawnych dla marshallera.  Jesli nie, to piszac 
"wrapper", ktory bedzie eksportowal takie "strawne" funkcje a sam 
zajmowal sie konwersja parametrow i wolal te "prawdziwe".
