Added Mode, SingalInfo, and AlertFlag to output

Added a few more data types from the PVTGeo block.
Mode tells which PVT mode the system is in
SignalInfo is a bit mask that tells which *signals* were used in PVT.  This
  is sort of a proxy for constellations, as each constellation has it's own
  separate signals.
AlertFlag is additional codes
Added TravGPS & options to skip some processing

Added the marker 'PT04', the Traveler GPS marker, to the list of
known GPS data stores.
Added and cleaned up some of the options to select specific sub-
functions of the script.  Now, you can turn off each of the four
SBF output types individually.
Shifting offset now applied a time of calculation

Previously, the 'shift' value, which allows the xPPSOffset values to be
applied with an arbitrary shift with respect to the TIC time stamps, was
actually applied on import of the xPPSOffset data.  This patch applies
the shift between TIC and offset time stamps during xPPOffset
corrections.

Also, an option was added to turn on calculation and plotting of the
frequency depature.
Updated README descriptions
Corrected data output format fixed

This patch changes the output format of the data files for xPPSOffset
corrected TIC measurements.  Now, the format is similar to the TIC
data file format, so it can be easiliy read back in by analyseTIC.py and
reploted at a later time (without xPPSOffset data present).
Added mkCLKns.sh

mkCLKns.sh extracts the "StationClkOffset" value, called CLK(ns) or
rx_clk_ns by CSRS, and stores it in a file next to the CSRS .zip
bundle using the same filename format as xPPSOffset and pvtGeo block
exports I created from the SBF data logs.
Added FFT to anlayseTIC

Still WIP, but I want to check in this code for the time being.
Merge branch 'nu' into dev
mkCLKns includes switch to UTC time from GNSS time
Added getCorrData.sh
Updated README.md file

Added brief comments about the new files that were added since the
last update of the README file.  More documentation is needed.
Merge branch 'nu' into dev

Many new helper scripts created on neutrino.  I'm going to import these
and work to integrate them with the main public branch, public.
Minor tweeks to GetCorrData.sh
SBF extaction scripts updated

 * Improved messaging. PVTGeo block codes and other block data is
 now written to STDERR when problems are encouterned, not just generic
 error message.
 * Improved error checking loging in both programs.
 * Unified header rules. Both scripts now have same header options
 and sbf2offset.py now outputs header by default
Merge branch 'nu' of https://github.com/PaulDeStefano/pythonsamples into dev

Pulled in changes to SBF extraction scripts
Adding newAnalyser.py WIP

This isn't even half completed yet, I just want to start tracking
changes.
More WIP on newAnalyser
Starting to take shape
Broken, but making progress

I hope
It's almost working
