Creates a BEQI2-directory structure and populates it with some
 relevant BEQI2-files. Users may wish to modify this directory structure
 and add their own data.


Tool for analysing benthos data. It estimates several quality
indices like the total abundance of species, species richness,
Margalef's d, AZTI Marine Biotic Index (AMBI), and the BEQI-2 index.
Furthermore, additional (optional) features are provided that enhance data
preprocessing: (1) genus to species conversion, i.e.,taxa counts at the
taxonomic genus level can optionally be converted to the species level and
(2) pooling: small samples are combined to bigger samples with a
standardized size to (a) meet the data requirements of the AMBI,
(b) generate comparable species richness values and
(c) give a higher benthos signal to noise ratio.
