Selenium Function Library + File Handler

Here is my first attempt towards building Selenium Function Library. Here is a class which deals with File handling. Hence test data can be externalized in to notepad, excel, word pad instead of hard coding it in Selenium Scripts. So you can fetch test data using excel, csv etc and supply it to Selenium, more over you can execute same Selenium script for different set of data.

Java jars which I used here are jxl and Apache HSSF
