// 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)

// http://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
