/*
 *  class config:
 *  provides interface for interacting with configuration files
 *
 *  The configuration file is written at _config_file_path, which resides in the folder
 *  given by _config_folder_path.The configuration files are stored in the following format:
 *      *field_name* = *field_value*
 *  The object reads the configuration file and exposes a map<string, string> for accessing
 *  and modifying fields
 *
 *  members:
 *      _config_file_path: ABSOLUTE path of configuration file
 *      _config_folder_path: ABSOLUTE path of configuration folder
 *      config_values: map for accessing configuration fields
 *
 *  methods:
 *      _init_config_file(): initializes config file with default values passed to it
 *      _populate_config_values(): reads configuration file and populates config_values
 *      write_config_file(): overwrites config file with contents of config_values
 *      get_folder_path(): returns _config_folder_path
