Merge pull request #40 from jread-usgs/master

Allow 'None' for solo_inputs, which will not be used in FWGS

I'm merging these, and opening a jira to implement tests for them, If you have time go for it, if I get time I'll to the tests.
Fixed the dodsReplace function so it is called as self.dodsReplace. Implemented tests for the dods switch and the None for startTime and endTime. Incremented version to 1.2.1 and made note of changes in CHANGES.txt

Fixed some broken stuff.
Fixed a bug with the stats in FWGS.
Merge pull request #42 from dblodgett-usgs/master

Fixed a minor bug in the stats list checker.
Reimplemented getAttributes to use lxml, it is now compatible with ArcGIS server WFS. Will implement tests later.
implemented a test against the geofabric hosted by sciencebase. Should probably identify a better test resource for the ArcGIS WFS test.
Reimplemented the getValues function. Things are so intertwined that this broke something else seamingly unrelated. GetValues is called by the getTuples method though and getTuples gets called by _getFeatureCollectionGeoType with what looks to be the attribute the_geom. This causes all kinds of troubles for my new method in getValues. Will have to separate the concerns ot these two methods.
Found the GeoServer creates gml very different from Arc. One uses a featureMembers element while the other uses a 'featureMember' collection of elements... I think I have this handled OK. I'm sure there's a better waym but this will do the trick.
Pulled a couple debug lines.
Commiting an unsaved fix to a test.
Fixed a hard coded the_geom, this is really close to working with ArcServer, might just be a bugon the GDP WPS now.
Little tweak to the last commit.
Found a stupid detail I was missing that was breaking things. This should be good up to submitting requests.
Incremented Version, modified CHANGES.txt, and removed now unused private methods.
