 == 1. Integral function calculation using trapeze, rectangle and Simpson method ==
+There are three methods which are using for calculation definite integrals in Fortran.
+First is rectangle method, where the function is integrated using segment integration 
+and like a resultant we obtain rectangle formula. Second is trapeze method and the same like
+in the first method after integration we obtain the trapeze formula. And the third method is
+Simpson method where the function which is integrated, is parabolic and after integration    
+we obtain Simpson's formula. In all methods are used segment integration, which means that
+interval of integration a and b is divided into N segments. The splitting points xn are  
+called nodes.   
+In this program we calculate the same integral but using different methods the get the 
+difference between each method .
