Unique Lines of Code - Feature Request

[exwhyz]

Are there any plans to add a means to compute the unique lines of code? Here is an example at the link blow - please scroll down to the last 2 charts at the bottom of the page for reference:

Also there is some discussion here on a related subject:

That's an interesting thought.

I might just do that!

Added... a primitive version of this into scc just then to see how difficult it would be. The answer being not very. I still need to fix this to work across languages, which might take some other flags, but it currently works across all files.

$ scc --uloc

which gives a number similar to the link mentioned. Now id like to see it as your first link shows broken down by language, but that's next on the list. Still some progress is there.

Added in a DRYness calculation which indicates how much repetition there is in the code. Higher values indicate less duplicate code hence making it more DRY as a solution.

Added to all output formats considering this done with the 3.3.0 release.
