- Created CGI scripts supporting queries needed by forthcoming web-enabled
  GetNHDStreamflowGageIdentifiersAndLocation and GetCatchmentShapefileForNHDStreamflowGage
- Modified ecohydrolib/nhdplus2/networkanalysis.py to allow choice of formats for
  getting catchment features associated with an NHD streamflow gage (shp and geojason)
- Updated GetCatchmentShapefileForNHDStreamflowGage to support changes to nhdplus2.networkanalysis
- Created install/kickstart.debian to begin documenting Linux installation instructions
- Initial implementation of web services client and server API for querying
NHDPlus2 streamflow gage information

- setup.py: Hard code version number of PySimpleSOAP to allow pip installation
  to succeed on CentOS

- centos.ecohydro-setup.tgz: Notes and configuration information for setting
  up NHDPlus CGI scripts under CentOS
bin/GetCatchmentShapefileForNHDStreamflowGage.py: Added option to
query from web service (the default)

bin/GetNHDStreamflowGageIdentifiersAndLocation.py: Added option to
query from web service (the default)

ecohydrolib/nhdplus2/webservice.py: Updated
getCatchmentFeaturesForStreamflowGage to return tuple of filename and
