Input: Atypia-Amplitude Signature   amp_list, Threshold for PIP detection T
Output: the sequence of the detected pip points pip_list
Method:
(1) m amp_list.length
(2) pip_list new List()           //initialize pip_list
(3) pip_list.add (amp_list.get(1))         //the first point of amp_list is added in pip_list
(4) Sub_PIP_Detection (1, m, amp_list, T, pip_list)   //pip  detection  is  performed at given range
(5) return  pip_list
