POLYGONSIGNATURE Polar signature of a polygon (polar distance to origin).

   DISTS = polygonSignature(POLY, THETALIST)
   Computes the polar signature of a polygon, for a set of angles in
   degrees. If a ray at a given angle does not intersect the polygon, the
   corresponding distance value is set to NaN.

   DISTS = polygonSignature(POLY, N)
   When N is a scalar, uses N angles equally distributed between 0 and 360
   degrees.
   
   [DISTS, THETA] = polygonSignature(...)
   Also returns the angle set for which the signature was computed.

   Example
   polygonSignature
