Extend Geoshape interfaces so objects can be copied/serialized

Hi david.wright@bksv.com,

I would like to propose to extends the GeoShape interfaces to be able to copy/serialized the objects. The current status and propose change is as following:

GeoPoint: It can be serialized by using x, y, z
GeoCircle: It can be serialized by using getCenter() and getRadius() and getPlanetModel()
GeoCompositeShape: It can be serialized by accesing shapes using size() and GetShape(int index)
GeoPath: add methods to the interface getPoints() and getCutoffAngle()
GeoPolygon: This is the most complicated one as we have different types:
1.- GeoCompositePolygon is just a composite
2.- GeoConcavePolygon and GeoConvexPolygon: Create a new interface for those polygons which exposes the points, holes, internaledges and concavity/convexity
3.- GeoComplexPolygons: Do nothing, they are too complex to be serialize??

I am intersested in accesing the discreatization of the polygons into convex and concave ones for other reasons as well. I think this should be expose as they end result can be used for other use cases.

Cheers,

I.
