Title: Fix, add missing, and properly format haddock documentation.

``` unionR ``` and ``` unionL ``` seemed redundant so I removed them. The fact is my brain was numb after working on the documentation so I may have missed the purpose.

The complexity annotations also need fixing but I'm getting dizzy.
Also there are a few odd sounding formulation, but as I'm not a native English speaker, I did not dare.
