39f8754217 Cleaning the terminal output and dumping most of the information in the log file. Better use of the glog library, logging can be seen also in Release, in real time by doing './gnss-sdr --logtostderr=1'. Update to latest version of Armadillo.

669910f6af Improving the way cmake detects GNU Radio. Switching from FindGnuradioXXX() to ConfigGnuradio.cmake. Fixed a typo in README. Tested in Mac OS X 10.9 and Ubuntu 13.10 64 bits, should work on other versions as well.

681bd60a58 Files to test an experiment performed by Luis Esteve in the framework of the Google Summer of Code (GSoC) 2012, with the collaboration of Javier Arribas and Carles Fernández, related to the extension of GNSS-SDR to Galileo.

9d34147e0f Major update to improve the GNSS-SDR pseudorange precision and correct some PVT bugs:
- Updated all available trackings to generate the tracking_timestamp_secs taking into account the remainder code phase.
- Updated the telemetry decoder to track the number of symbol shifted from the preamble start symbol (to be used in observables).
- Updated observables to align the reference channel symbol with the corresponding symbols in the other channels and compute pseudorranges using the common transmission time algorithm.
- Updated PVT to independize the display output rate from the RINEX and KML log files. New options available in config file!
- Some minor improvements and code cleaning.

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
