         * Release by hayzel (koppermind@panafonet.gr)
         This version has many valuable changes, though It may have some annoying bugs. Please if you are interested in opie-sheet try it hard, so I can fix some of them. Also If you want some other functions that must be here and are missing feel free to ask them. (no financial functions please. :)  I really hate them )
         -Fixed a bug with non closed parenthesis editing&recalculation infinite loop.
         -Added support for functions that can parse parameters not ONLY as numbers but also as strings.
         -Added many functions that cover many computational topics rendering opie-sheet a computational tool-spreadsheet at last. (total 90 functions!)
         -Maintained compatibility with the opie-fileformat.
         -New icons.
         -Found that the DataParser was not a real RPN compiler of the expressions. In fact it was returning faulty results in calculations, in both binary or unary operations. A1-A2-A3 was parsed as A1-(A2-A3). -A1 was parsed as A1.
         -Added new class "Expression" a general Parser for spreadsheet-expression. Imported from an old C# project of mine.
         -Now can also parse <>=!%&^|"" in expressions.
         -Added experimental Excel File format import!. The opie-sheet can import any excel file in BIFF7/BIFF8 format. These formats are used in Excel XP,2000,95. The Excel Importer class is in a good coding level.. BUT it is not complete. Only strings,numbers,formulas are imported. Not formatting rules. Not all the functions are converted in the functions of opie-sheet. Infact FEW functions are converted.
         -Fixed a bug with Sheet Recalculation. Added ReCalc() function. Opie-sheet was calculating wrong the values of expression in opening/importing. if a value needed was not loaded yet in the time of calculation. Solved with ReCalc() each time the active sheet is changing.
 
 
         *known issues:
         -if someone enters directly text as parameter to a string function the text renders as uppercase due to the calculation engine that uppercases all the parsing sentence.
         -randbetween return only integer part random... if both limit numbers are integers.
         -skew and kurt function give different results compared to kspread-oofice equivalents.
         -unstable parser Excel Class
         -string vars and string functions are not correctly handled by excel importer.
         -unicode strings are converted FINE in QString unicode format, but cannot be rendered fine if a suitable unicode font is not setuped as the default string. So the string is junked in the opie-sheet and may crash the parser.
 
         *TODOs:
         -surelly a much full-stable excel importer.
         -Cell Manipulation of many Data is really slow.... must change the QList data type. To a structure more efficient.
         -maybe some more functions.
         -maybe some kind of charts drawing?
         -maybe kspread or ooffice files import/export.
