As reported by @jonalv , it can be confusing what is happening when if the globber pattern does not catch any files.

The suggestion is to:

• Log when the globber starts, with the pattern used
• Issue a warning if the globber doesn't match any files at all

Describe the problem
PROTACs are a class of therapeutics that flag target proteins to a cell's waste disposal system, instead of the traditional binding to targets. It has been very promising due to its ability to tackle undruggable targets. However, problems still exist, such as designing the PROTACs, measure the degradability, understand the mechanism.

It would be a bit of fun to see if stk can handle building things like this: https://chemrxiv.org/articles/preprint/Isogonal_Weavings_on_the_Sphere_Knots_Links_Polycatenanes/12616268

Objective

Provide a German translation of the strings defined in headers/text.h.

Rationale

Users, especially in educative contexts, might want to use the software in their native language.
