Hi, I write this topic to make a suggestion to improve the MetaPhlAn documentation respecting GraPhlAn, in particular, I was reading [this section](https://github.com/biobakery/biobakery/wiki/metaphlan2#create-a-cladogram-with-graphlan) trying to know how to use GraPhlAn and I didn’t find the `export2graphlan.py` script anywhere because I thought it was part of MetaPhlAn or GraPhlAn, and only after some search I realized that this script was found [here](https://github.com/SegataLab/export2graphlan) and needed to be installed also. I think that this should be stated more clearly in the documentation of MetaPhlAn.

Thanks for your attention.
