Beginning work on WaterML 2.0 NetCDF.
Mapping FeatureDatasetPoint to WaterML.
Mapping FeatureDatasetPoint to WaterML. (2)
 Extending JAXB types. Adding tests for each.
Lots more JAXB classes mapped. Stuck on Shape.
Use new "combined" build of WaterML 2.
Added "time" to JAXB object.
* OM_Observation test still failing, and it may be awhile before it passes.
Added data variable to JAXB object.
* Includes conversion of UDUNITS to UCUM.
Finally converting NetCDF to valid WaterML!
* Currently, only datasets containing a single station with a single data variable are supported.
Added data variable to JAXB object.
* Includes conversion of UDUNITS to UCUM.
Added support for writing multiple stations. Still only 1 var.
* Deleted a lot of unnecessary tests. There's only the one on NC_Collection now.
* Made the XPATH documentation more consistent.
Added WaterML XML bindings generation code to thredds.
* Moved other WaterML-related code around to create a multi-module maven project.
Added WaterML button to ToolsUI.
* There may be a bug in the cdm wrt data variable identification.
* It's still a bit kludgy, but it's not like it needs to be production-ready.
* Refactored waterml-bindings and waterml-converter a bit.
Added data variable selection to WaterML button.
* Refactored waterml-converter classes to accept and pass a VariableSimpleIF argument.
* We seem to only be able to write a FeatureDatasetPoint's observations once, then an empty WaterML doc is produced. Maybe we need to reopen the dataset?
Finished WaterML button.
* Fixed a bug in NC_Collection that was only allowing a point dataset to be converted once.
* Added an error popup if the dataset's feature type isn't STATION.
Added WaterML v2.0 writing to ToolsUI->FeatureTypes->PointFeature.
Finished adding WaterML v2.0 writing to target-4.5.0.
* Changed instances of "4.4.3-SNAPSHOT" to "4.5.0-SNAPSHOT".
* Changed versions of errdap-unit-converter and waterml-bindings-v_2_0_1 to "1.0.0".
* Replaced several redundant catch blocks to Java 7's multi-catch.
Fixed merge conflict.
