//Si programa skirta diodo VACH koeficientu nustatymui 
//naudojamasi sroves priklausomybe nuo ytampos
//Diodo VACH yra aprasoma formule, kurioje yra du nezinomi koeficientai
//Optimizavimas vykdomas pagal
//absoliutine reiksme. Optimizavimo programa apskaiciuoja
//optimalius koeficientus ir juos istacius i VACH formule
//gauname optimalia diodo charakteristika ir galime geriau
//parinkti reikiama dioda
