+detectMultiScale(image, scaleFactor, minNeighbors): 
+    This is a general function to detect objects, in this case, it'll detect faces since we called in the face cascade. 
+    If it finds a face, it returns a list of positions of said face in the form “Rect(x,y,w,h).”, if not, then returns “None”.
+Image: 
+    The first input is the grayscale image. So make sure the image is in grayscale.
+scaleFactor: 
+    This function compensates a false perception in size that occurs when one face appears to be bigger than the other simply because it is closer to the camera.
+minNeighbors: 
+    This is a detection algorithm that uses a moving window to detect objects,
+    it does so by defining how many objects are found near the current one before it can declare the face found.
