/** DirectoryList class
 *
 *  Simple interface to get file name list of directory
 *  which is specified by path.
 *
 *  The DirectoryList instance will be an object of "std::vector<std::string>".
 *  
 *  This library works on local strage on mbed as well as on USB strage. 
 *  (It has not been tested on SD yet.)
 *
 *  Example:
 *  @code
 *  #include "mbed.h"
 *  #include "DirectoryList.h"
 *
 *  LocalFileSystem local( "local" );
 *  
 *  int main(void)
 *  {
 *      DirectoryList   dir( "/local" );
 *
 *      if ( dir.error_check() )
 *          error( "directory could not be opened\r\n" );
 *
 *      for ( int i = 0; i < dir.size(); i++ )
 *          printf( "%s\r\n", dir[ i ].c_str() );
 *  }
 *  @endcode
