How can I add a manual page number input feature to my collection pages?

[davemdns]

Hello, I'm trying to implement a feature for my collection pages. I've seen on a couple of sites the ability to jump page numbers by manually inputting it. In certain collection pages, there's too much to go through, so only the first page numbers (ie. 1 2 and 3) and the very last numbers are shown. I have a picture to give a better explanation.

I'm just trying to implement this. Any help would be much appreciated.
