Merge pull request #5 from USGS-CIDA/master

Up to date with execute changes that dblodgett made
This fix will catch errors associated with the attempt to retrieve or parse the status document. isComplete is true ONLY for a process status of success. Any other valid WPS status keeps isComplete False. We are not happy with the "print" behavior and need to work with implementors for a better solution. The standard "Exception" may not be the most appropriate either, but will work for now.
Just a little final cleanup.
Implemented correct multiplicity for FeatureWeightedGridStatistics. Added test and example coverage.
Implemented another test to catch changes to function input names. A few tweaks to the previous additions as well.
Merge pull request #35 from dblodgett-usgs/master

A workable solution to network glitches and server restart events. Also added the correct multiplicity for featureWeightedGridStats.
Implemented better handling of the value input of FWGS. It now takes the string 'all_values' which creates a WFS query that returns all values. I don't think we want the default behavior to be all values, so this should be a good solution.
Implemented a couple tests for the _getFeatureCollectionGeoType function.

Minor changes. Trying to fix jenkins build.
Changed the all_values string to the default None to return all polygons according to a user request. Also changed inputs from string true or false to proper python booleans. This change is backward compatible.
