Shape files of type "Polygon 3D" cause errors during sampling such as the 
following:

loading shape records error: /data/ala/data/layers/ready/shape/tams_reserves: 
java.nio.BufferUnderflowException
java.nio.BufferUnderflowException

A workaround is exporting the shape file from the database using pgsql2shp, see 
:http://code.google.com/p/alageospatialportal/wiki/ContextualLayerLoadProcess#3d
_polygons

the intent of the PolygonZ class is to handle 3d polygons. Either this class 
should be fixed, or it should be removed and a more appropriate error message 
should be thrown when a 3d polygon is found during the sampling process.

Can we check for a 3d polygon on import (which I presume is the only way a 3d 
can occur?) and generate 2d version as above?
