// Original file header of ParseXL (used as the base for this class):
// --------------------------------------------------------------------------------
// Adapted from Excel_Spreadsheet_Reader developed by users bizon153,
// trex005, and mmp11 (SourceForge.net)
// https://sourceforge.net/projects/phpexcelreader/
// Primary changes made by canyoncasa (dvc) for ParseXL 1.00 ...
// Modelled moreso after Perl Excel Parse/Write modules
// Added Parse_Excel_Spreadsheet object
// Reads a whole worksheet or tab as row,column array or as
// associated hash of indexed rows and named column fields
// Added variables for worksheet (tab) indexes and names
// Added an object call for loading individual woorksheets
// Changed default indexing defaults to 0 based arrays
// Fixed date/time and percent formats
// Includes patches found at SourceForge...
// unicode patch by nobody
// unpack("d") machine depedency patch by matchy
// boundsheet utf16 patch by bjaenichen
// Renamed functions for shorter names
// General code cleanup and rigor, including <80 column width
// Included a testcase Excel file and PHP example calls
// Code works for PHP 5.x
// Primary changes made by canyoncasa (dvc) for ParseXL 1.10 ...
// http://sourceforge.net/tracker/index.php?func=detail&aid=1466964&group_id=99160&atid=623334
// Decoding of formula conditions, results, and tokens.
// Support for user-defined named cells added as an array "namedcells"
// Patch code for user-defined named cells supports single cells only.
// NOTE: this patch only works for BIFF8 as BIFF5-7 use a different
// external sheet reference structure
