Added string format with positional arguments.

Reading first line to grab headers. Also using with to auto-close the file, much in the same way that using() does in C#.

Parses CSV header row. Assembles a format string. Iterates each line, applying the format string, writing the result to the specified XML file.

Removed unneeded print statement.

Fixed some tabbing issues.

Removed some unnecessary print statements.
