At long last

I have written this code out at least 4 times, only to delete it some way or another while trying to get it up on github. Wish they made an easier way to contribute to them on atom. Like being able to load packages from different directories. Anywho, I added in another option to have the lines show the top and bottom of a selection/selections. It's disabled by default but can be enabled by the newly added hotkeys. Also added one for the previous pulled stuff I added.
Last but not least, I updated the readme with a screenshot, and gave myself a little credit. ;)
