simplified nwispy_logging to only make 1 file called error.log
simplified tests in filereader using all()
adding tests to helpers
simplified logging to only have one input parameter; also catching errors if all data points are nan
refactored some code in nwispy_filereader; added convert_to_float() and compute_simple_stats(); these functions handle warnings and errors specific to nwis files
re-ran datafiles and webservice-requests to reflect better error messages
