C# WORD, and replace text, plus hebrew trick examlpe

the WordHandler class is the hard work of one of our ex-engineers.
pls remember that the number of parameters passed changes with the office versions
also u need to put the right Microsoft.Office.Interop.Word version, and its not according the office (word 14 is for office 10)
the trick is mine - the text backworded so a added in the word template val2 after val and it did the trick
