0a62725445 - Improved speed for samples inconsistency check in tracking modules, and 
- Added a total elapsed run time counter in main: now it is possible to compare the post-processing time with the signal duration. The elapsed time is reported in STD::COUT when GNSS-SDR finish the main thread.

0d598a7188 Added implementation of plain cordic class in tracking/libs. Added a corresponding test. The implementation is slower than standard sin and cos implementations, so it is not used in the receiver. The test will fail otherwise, indicating that this should be used instead of standard functions.

27b5074152 gnss-sdr now accepts a --config_file flag for specifying the configuration file: 
./gnss-sdr --config_file="my_receiver.conf" 

and another --signal_source flag that, if specified, overrides the file in the configuration:

./gnss-sdr --signal_source=/path/to/file.dat

Requires gflags 1.6 or later.

69b8ac00dc - Major changes: 
- The executable file and the default configuration file is now changed from "./install/mercurio" and "./conf/mercurio.conf" to "./install/gnss-sdr" and "./conf/gnss-sdr.conf", respectively.
        - Configuration file structure changed to define in a single entry the internal sampling frequency (after the signal conditioner). NOTICE that this change affects the all the adapters (acquisition, tracking, telemetry_decoder, observables, and PVT). All the adapters are now modified to work with this feature.
        - Moved several in-line GPS L1 CA parameters (a.k.a magic numbers..) to ./src/core/system_parameters/GPS_L1_CA.h definition file.
        - Tracking blocks now uses DOUBLE values in their outputs.
        - Observables and PVT now are separated. PVT and their associated libraries are moved to ./src/algorithms/PVT
        - Temporarily disabled the RINEX output (I am working on that!)
        - GNSS-SDR screen output now gives extended debug information of the receiver status and events. In the future, this output will be redirected to a log file.

- Bug fixes:
        - FILE_SIGNAL_SOURCE now works correctly when the user configures GNSS-SDR to process the entire file.
        - GPS_L1_CA_DLL_PLL now computes correctly the PRN start values.
        - GPS_L1_CA_DLL_FLL_PLL now computes correctly the PRN start values.
        - Several modifications in GPS_L1_CA_Telemetry_Decoder, GPS_L1_CA_Observables, and GPS_L1_CA_PVT modules to fix the GPS position computation.

- New features
        - Tracking blocks perform a signal integrity check against NaN outliers before the correlation process.
        - Tracking and PVT binary dump options are now documented and we provide MATLAB libraries and sample files to read it. Available in ./utils/matlab" and "./utils/matlab/libs"
        - Observables output rate can be configured. This option enables the GPS L1 CA PVT computation at a maximum rate of 1ms.
        - GPS_L1_CA_PVT now can perform a moving average Latitude, Longitude, and Altitude output for each of the Observables output. It is configurable using the configuration file.
        - Added Google Earth compatible Keyhole Markup Language (KML) output writer class (./src/algorithms/PVT/libs/kml_printer.h and ./src/algorithms/PVT/libs/kml_printer.cc ). You can see the receiver position directly using Google Earth.
        - We provide a master configuration file which includes an in-line documentation with all the new (and old) options. It can be found in ./conf/master.conf

34d1c5110b GNSS-SDR Major changes: 
New tracking libraries:
        -  tracking_discriminators: Library with a set of code tracking and carrier tracking discriminators that is used by the tracking algorithms. (fully documented, including math algorithms using doxygen!)
        -  tracking_2rd_DLL_filter: Class that implements 2 order DLL filter for code tracking loop.
        -  tracking_2rd_PLL_filter: Class that implements 2 order PLL filter for carrier tracking loop.
        -  tracking_FLL_PLL_filter:  Class that implements hybrid FLL and PLL filter for tracking carrier loop.
        -  CN_estimators: Library with a set of Carrier to Noise estimators and lock detectors. (fully documented, including math algorithms using doxygen!)

    Tracking:
        - gps_l1_ca_dll_pll_tracking: The existing DLL + PLL tracking module, which is the K.Borre and D.Akos one, is now completely re-factored. Now uses the above described libraries.
        - gps_l1_ca_dll_fll_pll_tracking: This is a brand new tracking module, which implements the FLL assisted PLL described in Kaplan (2nd edition). (also documentedwith references)

    Configuration options:
        - The following tracking parameters are added:
            ;######### TRACKING CONFIG ############
            ; Tracking.implementation=GPS_L1_CA_DLL_PLL_Tracking or GPS_L1_CA_DLL_FLL_PLL_Tracking 
            Tracking.implementation=GPS_L1_CA_DLL_FLL_PLL_Tracking
            ;PLL filter bandwidth in Hz.
            Tracking.pll_bw_hz=50.0;
            ;DLL filter bandwidth in Hz.
            Tracking.dll_bw_hz=2.0;
            ;FLL filter bandwidth in Hz.
            Tracking.fll_bw_hz=50;
            ;filter order: choice between 2 or 3 at this moment, only for FLL assisted PLL
            Tracking.order=2;
            ;Correlator space in chips units
            Tracking.early_late_space_chips=0.5;

Other files have also been modified with minor changes to adapt to new modules or minor bug fixes.
