Title: ContourProcess patch for GEOT-4069.

See http://jira.codehaus.org/browse/GEOT-4069.
This patch works around the JAITools Contour op issue by manipulating the levels - based on a scan of the raster values - before passing them to JAI. Any level that is equal to a raster value is increased by a small enough amount not to match or exceed any higher raster value (or level value). When processing the line strings returned by JAI, we then translate the level values back so that the feature collection we return from the ContourProcess reflects the original input level values.
