Small fixes to all object files

Small Fixes:
STDS
- renamed object name
- made recursive print, shrt_str, and progress bar len ALL semi-private
- moved list of Carriers to data_utils. Imported at beginning of file
as Carriers
- no longer pass sys.argv through constructor. Used directly by
loadRawData()

SpeedTestFile
- NetworkType -> DeviceType
- made FileStreamLoc, ignored text, and short_str semi-private
- added more function descriptors
- import more stuff from data_utils
- loadHeaderInfo() no longer needs list of Carriers. Uses Carriers from
data_utils

TCP, UDP, Ping, and Indiv Test
- Made error info semi-private. added ErrorType variable

Larger Fixes:
submain_obj
- changed flow of UI
- ask user about recursive print and short str

DB_API
- started work on storeFile(). Using placeholder queries

Added .in files for quicker testing
