Section 5.1: Mereological closure operations

Lemma 5.1. Proof output for (M-I) with input file.

Lemma 5.2. Proof output for (M-S) with input file.

Lemma 5.3. Proof that (M-C) is sufficient to prove that L is uniquely complemented and thus Boolean with input file;
Proof that if L is Boolean and thus uniquely complemented, (M-C) must hold with input file.

Lemma 5.4. Proof output for (O-Ext) with input file, this is not really new, since it is well known that overlap is extensional in contact algebras defined over Boolean lattices.
