What it does
============

Subsets the data in ampvis2 objects based on taxonomy and returns the subsetted object.

The Galaxy tool calls the `amp_subset_taxa
<https://kasperskytte.github.io/ampvis2/reference/amp_filter_taxa.html>`_ function
of the ampvis2 package.

The taxonomy subset is done by providing a tax_vector of taxa names which are
then matched to the taxonomy table, where all other taxa not matching the
"Taxa to keep" (``tax_vector``) are removed. If "Remove" is enabled, then the
matching taxa are the ones being removed instead. The taxa names 
will be matched in all columns of the taxonomy table.
