[gdal-dev] Length method for geometries in bindings

[Ari Jolma]

Folks,

I added a Length() method for geometries into bindings. The method 
re-dos a simple euclidean distance as the get_Length of OGR proper is 
not exposed.

I hope this is ok. Length is in OGC SF with that name. However, the 
standard specifies that the length should be in its associated spatial 
reference and that's not the case here.

The method checks for geometry count and is recursive if count is > 0. 
The syntax  OGRGeometryShadow_Length for calling the method itself works 
in swig/Perl but I'm not sure about other languages. Could other swig 
developers check?

Regards,

Ari
