With the file reference_data/basis_sets/default/mini.nw present, it makes it a tad bit harder to do development if only the sto-3g basis set is used in the master branch. With the file present, the resulting development workflow of generate_basis.py results in the mini basis set being generated, which leads to extra cleaning of the mini basis set files that are generated.
My suggestion is to either add the mini basis set data to the master branch, or to remove mini.nw to prevent generating the basis set files. What do you all think?
