Same as last, don't know what's up.
Modified program to allow for input of manual range.

By specifiying a value in the KWARGS dict. you can put the range in manual
mode. I haven't added a way of setting this in the UI yet.
Changed output to CSV.

Changed the output format from tab-delimeted .txt file to a comma delimted
.csv file. I did this because it is easier to make excel auto-open a CSV
than a .txt so it will be more convient.
