Purpose

---

      Distance in meters between two points given as structures.

Category

Calling Sequence

---

      sep = ell_point_sep(p1, p2)

Inputs

---

      p1, p2 = Two given points. in
        Points are structures: {lon:lon, lat:lat}.

        AZI=azi Returned 2 element array with azimuths [a1,a2]
          where a1 is azimuth from p1 to p2, and a2 is azimuth
          from p2 to p1.
        /CHECK_ZERO Check for 0 distance case. Will hang if
          the points are the same without this.

Outputs

---

      sep = Distance between the points in meters. out
        Distance is the ellipsoidal geodesic distance.
