Purpose

---

  Compute the perimeter of a polygon defined by a set of x/y points

Calling Sequence

---

  p = perimeter(x, y)

Inputs

---

  x: List of x points
  y: List of y points

Outputs

---

  Perimeter defined by connecting x/y pairs. The perimeter includes
  the line segment from the last x/y pair to the first x/y pair.
  METHOD SUMMARY:
  The length of the line segment connecting each x/y pair is computed
  using the pythagorean theorem in double precision. Lengths are
  summed.
