Carles Fernandez b67be26aa2 Explicitly informs about the logging path and how to change it with the --log_dir flag. This is specially useful in MacOS, where the default path is not /tmp but a lengthly, not-easy-to-memorize folder name. This change requires Boost 1.45 or above. Ubuntu 10.10 shipped Boost 1.42, so this change breaks compatibility with Ubuntu 10.10. Feel free to remove the boost::filesystem::temp_directory_path() call if you want to continue using Boost 1.42. The --log_dir flag will still work.

Carles Fernandez 0d8b26de30 Revert changes of bits_slices struct since it was not decoding the navigation message properly

Carles Fernandez f6892a8bf3 It seems that definitions such as 
const bits_slice INTEGRITY_STATUS_FLAG = {{23,1}};

used in GPS_L1_CA.h are not allowed in the C++11 standard since they do not correspond to any valid constructor. This is accepted by the current version of gcc (probably due to backward compatibility with C and earlier versions of C++), but it *could* not be accepted in future versions. This can be fixed by putting the struct into a std::vector. I don't know if this is the best way but it seems to work well and does not implies major changes in the code.

There is another issue with the Gnss_Synchro class. Since it had a constructor and a destructor, it could not be considered a POD (Plain Old Data) structure and this has some limitations: while gcc and the C99 standard allowed an array's size to be determined at run time, this extension is not permitted in standard C++. This issue has implications when passing Gnss_Synchro through memory between signal processing blocks. In order to fix this, I have removed the Gnss_Synchro.cc implementation and now this is a header-only class where the array size can be determined at compile time
