Asa's fuzzy protologic

One sort of proto-logic works by verifying if a subset of symbols is present in a certain set. (Principles of Quantum Artificial Intelligence, Andreas Wichert, World Scientific, 2014, pg 31 ).  The set is represented by a vector which is divided into sub-vectors.   Asa searches for sub-vectors in this way but it is satisfied with an approximate rather than an exact match.
