added another test for spatial data and a couple more spatial data files
having working batch for delta factors and xml files; however, if xml data has NAN values, then the plotter will not plot NaN values when those values correspond to a date value; need to program against this because WATER does spit out NaN values for some basins for some reason; also added some new data sets
added tests for point shapefiles
added tests for point shapefiles in spatialvectors and spatialdata_viewer along with adding two additional spatial datasets
Merge branch 'develop'
