Make skipping scheme nicer

[LanaLubecke]

From lines 152-157 in "clipping_processor.jl" I implemented a "skipping scheme." Essentially because I am iterating through a list that I am actively adding to. So if I add a new element to the list at some stage in the for loop, there is a chance I might run into it again as the for-loop goes through the list, but I do not want to process it twice, hence the skipping scheme.

I think the way I approached getting the functionality I wanted was convoluted and there is probably a better way to do this.
