Bigecyhmm

Add

* scripts to create diagram figures in Python using pillow.
* pillow as dependency.
* templates folder for biogeochemical diagram creation.

Add

* `scripts` folder with script `create_hmm.py` trying to create HMMs and `draw_biogeochemical_cycles.R` to draw geochemical cycle diagrams (modified from METABOLIC script).
* `R_diagram_pathways.tsv` in database folder.
* creation of metadata file.

Modify

* update HMMs database with: `aspA`, `nod`, `fthfs`, `mcrG`, `mtaB` and `mtbA`.
* set HMMs score threshold to 40 and evalue to 1e-5 to extract functions.

Add

* diagram files creation.
* `R_diagram_pathways.tsv` in database folder.

Add

* bigecyhmm command line and python functions.
* HMMs used in `hmm_databases` folder.
* Readme.
