 Usage:  y = lprotint (t, a, p)  
 
 Input:

  t                      scalar (argument) 
                         
  a                      (p+4) x 1 vector (coefficients of polynomial) 
                         
  p                      integer 
                         
 Output:

  y                      scalar (value of integral)
