[PATCH] Set Ignored Fields

[wonder]

The attached patches implement support in OGR for optional ignoring of fields, geometry and style as specified in RFC29:

http://trac.osgeo.org/gdal/wiki/rfc29_desired_fields

The "base" patch implements the generic infrastructure, the "shape" patch implements the support for shapefile driver.

[wonder]

Please could you review the patches and post your comments so that it can be included into trunk soon?

Thanks

Martin

I've marked the RFC as adopted based on the voting history information and I will review the diffs and apply.

Patches apply and build cleanly - but I've changed bool to int. Hmm, no swig bindings or test suite ... this will take a while.

[warmerdam]

I have applied the patch with a few adjustments (bool), and addition of swig bindings in trunk (r20885). I've also introduced minimal testing of the shapefile implementation in the autotest suite (r20884).
