 Usage:  y = simpsonint (func, a, b, m)  
 
 Input:

  func                   text, name of the procedure where the function is defined 
                         
  a                      d vector, containing the begining points of the intervals. 
                         
  b                      d vector, containing the end points of the intervals. 
                         
  m                      d vector, 2 * m(i) is the number of subintervals in the i-th dimension. 
                         
 Output:

  y                      scalar, value of the integral
