Cleaning up the parser logic. Put it into its own class. Going to start working on supporting multiple simulation tags.
Merge branch 'dev'
Added support for multiple simulation tags. Parser can also tell tags that are not present. Need to do some more work on validating that the user entered all the required values for the xml file.
