Earth-20100311

This release of JMARS for Earth adds numerous useful new features to the shape layer, and greatly improves the stability and performance of several common operations.

• The shape layer now has experimental support for reading KML files. Network links and polygons with holes are unsupported, but planned.
• The shape layer can now read and write csv files. See the shape layer documentation at http://jmars.mars.asu.edu for details.
• The shape layer has a new style editor that makes it easier to set defaults for things like fill color and line thickness, and makes it possible to control what columns styles should be draw
  n from. A common use of the latter feature is changing the text label to come from a column of your choice, instead of having to use the name "Label" and force the type to 'string'.
• The shape layer has a new column editor. With it, you can now set up some columns to be automatically calculated. There are functions to compute polygon area, line and polygon perimeter, l
  ine azimuth east of north, center latitude, center longitude, and to sample pixel values from a map layer. The sampling feature will compute the minimum, maximum, average, or standard deviation
  of those map pixels that lie underneath each feature in the shape layer.
• The 'Paste' button on the stamp layer's Rendered tab now works for all selected images at once. This makes it easy to colorize one image, and then apply the same colors to all of the other i
  mages.
• Numerous stability and performance improvements throughout.
