  public bool[] get_boolean_list (string group_name, string key) throws KeyFileError
Returns the values associated with key under group_name as booleans.
If key cannot be found then null is returned and throws is set
       to g_key_file_error_key_not_found. Likewise, if the values associated with key cannot be 
      interpreted as booleans then null is returned and throws is set to 
      g_key_file_error_invalid_value.

| key | 
           a key  |
