Versioning

Versioning has been added to the lit review a the different approaches to integrating IBM's clear case with the comparison tool have been investigated. This was very interesting there were 2 options one to use triggers to trigger the application to launch passing in the 2 files and another option of using ClearCase Automation Library (CAL) COM object with Java. Rick Dunn and Dean Godfrey were useful resources to tap into as theny both have previous experiance in this field. I am now up to 2000 rough words. Good progress!
