CMakeLists.txt:
  -Added include(CMakeFindBinUtils); Currently not used; It setups
various CMAKE_ variables that can be used during compiling;
  -Changed the compile flags to be -g0 and -s for Release builds;

src/CMakeLists.txt:
  -Switch from using the command "dpkg --print-architecture" to using
${CMAKE_SYSTEM_PROCESSOR};
  -Added a comment showing some of the errors that crop up when running
lintian on the built DEB;
  -Added a comment relating to SONAMEing of libraries;
Additional tests for (multiple_errors, stream_output);
tests/CMakeLists.txt:
  - Build commands for stream_output_checks.cpp, multiple_errors_checks.cpp

tests/to_fixed_string_checks.cpp
  - Comment added; TODO convert to a fixture testing;

tests/symmetric_error_checks.cpp
  - Removed an empty line;
inc/stream_output_proxy.hpp:
  - Changed to_string to the now implmented to_string_symmetric for the
    error_output_proxy (reasoning, need a default output); Creates tigher
    coupling between stream_output_proxy and symmetric errors (BAD);

src/symmetric_error.cpp
  - Added <tuple> header (because of tuple return type for
    to_tuple_multi_errors);
  - Replaced string_stream code with calls to to_fixed_string;
  - Implemented multiple error code; [x_1 +/- e_1 +/- ... +/- e_n]
  - Implemented to_string_no_exponent; (initial case of column aligned numbers);

src/stream_output_proxy.cpp
  - Added implementation of to_string_symmetric and to_latex_string_symmetric
