Calculate auxiliary information about preprocessings we generate

[AmroAlJundi]

Preprocessing outputs like reordering and partitionings can often have their own features to measure their quality. For example, for an edge-based partition, the number of cut edges. Calculating these metrics for users can be very useful.

These functions can either be preprocessing (classes with implementations etc.) or simple helper functions that we place in bases.

I believe simple helper functions added to bases make more sense. Otherwise, the preprocessing namespace will be very crowded. In addition to this, pre-processing must target only and only formats. If we decide to set the only communication medium between the user and the library as formats, we may consider these types of functions as a part of the namespace. Lastly, these metrics sound more like post-processing rather than preprocessing :).

Preprocessing post-processing 🤔
