first working version of audio file loder. Loads bach clip from the apps->audio-file-loader->bin->data->sounds foler. Three classes: SoundFileLoader does the loading and parsing of thefile with libSndFile. audio samples are kept in AudioFile and analysis of features are kept in AudioAnalysis, at this stage just chromagramm and basic energy
