Bug Fix & Updates

mkRINEX+CGGTTS.sh: fixed major bug in output naming
New SBF extraction tool: sbf2GLOtime.py
Updates of other SBF extraction tools documentation/comments
Bug Fixes & sbfExport function

mkRINEX+CGGTTS: added new function sbfExtract() that makes adding
new extractions much easier.  Probabily will be the last time I use
it ;-)

sbf2GLOtime
sbf2dop: extraction scripts had syntax error in the help text. Fixed.
mkRINEX: expand --noclobber option to all data

--noclobber now applies to all data.  If used, it prevents over-
writing final files (in organizedData/...) if they already exist.
This makes it easier to run on more data; it will process all data
matched by the file pattern, but only store results that were not
already processed.
