Fingerprint term indexing

Fingerprint term indexing, based on the paper of the same name by S. Schulz.

NOTE: less efficient, it seems, than NPDtree

type fingerprint_fun

A fingerprint function is a list of positions.

To compute the fingerprint of a term, we map each position to a feature; fingerprints can then be compared for potential unifiability/matching.

val fp3w : fingerprint_fun

val fp4d : fingerprint_fun

val fp4m : fingerprint_fun
