-// 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
