Integrate global output path into sctoolbox
We need a class/functionality to set a global output path after importing sctoolbox. Similar to scanpy, might be something like:
import sctoolbox
sctoolbox.figure_prefix = "../figures/QC_"
sctoolbox.anndata_prefix = "../anndata/QC_"
Defaults should be empty string. Writing of figures is easily set within sctoolbox.utilities.save_figure
. Saving of other types e.g. anndata might be controlled in a separate write_anndata
function.
