/** Examples
 *
 * Example 1:
 * if ( $xlsx = SimpleXLSX::parse('book.xlsx') ) {
 *   print_r( $xlsx->rows() );
 * } else {
 *   echo SimpleXLSX::parseError();
 * }
 *
 * Example 2: html table
 * if ( $xlsx = SimpleXLSX::parse('book.xlsx') ) {
 *   echo $xlsx->toHTML();
 * } else {
 *   echo SimpleXLSX::parseError();
 * }
 *
 * Example 3: rowsEx
 * $xlsx = SimpleXLSX::parse('book.xlsx');
 * print_r( $xlsx->rowsEx() );
 *
 * Example 4: select worksheet
 * $xlsx = SimpleXLSX::parse('book.xlsx');
 * print_r( $xlsx->rows(1) ); // second worksheet
 *
 * Example 5: IDs and worksheet names
 * $xlsx = SimpleXLSX::parse('book.xlsx');
 * print_r( $xlsx->sheetNames() ); // array( 0 => 'Sheet 1', 1 => 'Catalog' );
 *
 * Example 6: get sheet name by index
 * $xlsx = SimpleXLSX::parse('book.xlsx');
 * echo 'Sheet Name 2 = '.$xlsx->sheetName(1);
 *
 * Example 7: getCell (very slow)
 * echo $xlsx->getCell(1,'D12'); // reads D12 cell from second sheet
 *
 * Example 8: read data
 * if ( $xlsx = SimpleXLSX::parse( file_get_contents('http://www.example.com/example.xlsx'), true) ) {
 *   $dim = $xlsx->dimension(1);
 *   $num_cols = $dim[0];
 *   $num_rows = $dim[1];
 *   echo $xlsx->sheetName(1).':'.$num_cols.'x'.$num_rows;
 * } else {
 *   echo SimpleXLSX::parseError();
 * }
 *
 * Example 9: old style
 * $xlsx = new SimpleXLSX('book.xlsx');
 * if ( $xlsx->success() ) {
 *   print_r( $xlsx->rows() );
 * } else {
 *   echo 'xlsx error: '.$xlsx->error();
 * }
